Types of servo motors: The brushless servo motor

Published on: 24 July 2019 Last Updated on: 19 January 2022

Essentially, a brushless servo motor is a machine capable of developing high torques in order to oppose any effort that tries to take it out of synchronism. The name brushless comes from the simple fact that it does not have brushes and this is a way to differentiate it from other types of servomotors. Compared with other types of motors, the inertia of a brushless servo motor is substantially less. Both these characteristics – important overloads and reduced inertias – are appreciated and useful features for movement control because they allow rapid accelerations and decelerations, as well as precise position control at high speeds.

The most commonly used brushless servo motors in the industry, are those formed by a segmented stator in which the space filled with copper is almost double that in the traditional ones. This allows developing a greater power within a lower volume. Constructively, the brushless servo motor has a stator with a laminated core and a uniformly distributed three-phase winding. The rotor is constituted by a group of magnets fixed on the axis of the rotation. The shape of the rotors varies according to the design and can be cylindric or with outgoing poles.

Due to the high centrifugal forces to which they are submitted during the acceleration process, the fixing of the magnets to the rotor has been one of the critical points in the construction of brushless servo motors. This has been solved by using mechanical fixings of different types glued together using special adhesives.

In order to compensate for the greater amount of thread in the slots and its greater generation of heat, the free space of the winding is filled with heat-conducting resin. The rotor incorporates a series of permanent magnets that provide greater flow density and better performance.

The positioning time is reduced thanks to the reduction of rotor inertia that allows reaching high speeds in short times.

The Main Characteristics of this type of servo motor are:

Performance and high torque
Reliability of operation
Low maintenance
Great accuracy in speed and position control
Very high-speed capacity
Very low rotor losses
Rotor with low inertia
Closed construction, useful for working in dirty environments
Wide range of powers (from 100 w to 300 kW)

The main advantages of the brushless servo motor are given by the possibilities that this type of motor offers in the control of its speed and positioning.

Moreover, the possibility of construction of brushless servo motors allows the adaptation of the same to diverse industrial applications. The brushless servo motors of compact structure, incorporate within it an encoder absolute which provides information on the status of the process to the controller. Those who work in a vertical position, incorporate a mechanical brake on which blocks the axis in case of lack of tension to avoid possible falls of parts in case of failure.

Inside the brushless servo motor is included as an element for the control. The encoder is formed by an electronic circuit, in which a laser diode emits a beam of light, which is interrupted by the grooves of a metal foil, giving rise to a flashing signal. Each signal, through the corresponding connector cable, arrives at the control element for processing.

Is AI Changing The Insurance Sector?

A lot of people are excited about the AI revolution. Various industries will see many changes as artificial intelligence comes into more active use. One of the more interesting uses for it is in the insurance industry. As one of the world's largest and oldest types of business, integrating new technologies should not be a new thing. Artificial intelligence has multiple purposes, and insurance companies can use all of them. Underwriting and pricing One of the essential tasks for insurance is assigning a price and rating for every client. An insurance underwriter determines the risks that a customer faces and assigns them a price so that the insurance company has a good chance of profit. It can be a complex process that looks at various factors to determine the optimum price. The entire thing can take days or weeks. However, with an insurance rating engine, which is an AI that does the underwriting process automatically, it can be done much faster. Faster pricing can make a difference during sales since potential clients know the price faster. Additionally, the process can be further accelerated as more data comes in. Customer service Regarding customer service, insurance inquiries can come in at any time. While call centers can accommodate them, you can reduce customer service demands using chatbots and automated systems. The company can then reserve the actual agents for emergencies and complex inquiries. No need to bother your team with common questions and basic inquiries when the AI can handle them. Claims processing Another process in which AI can help is claims processing. Insurance claims require some calculations that would normally take days. When the claim comes in with AI, the calculations can take minutes. The only delay would be the approval process. However, immediately making the claim amounts available can be a big help, especially during medical emergencies. Automating the claim lets agents focus on the important work instead of spending days processing claims. More claims can be processed with their help so that an insurance company can provide maximum service. Fraud detection While actual investigation and footwork are still necessary, detecting fraud can start with noticing discrepancies. That is excellent work for AI since it can easily go through the data and detect them. No need for people to go through the data themselves. The AI can look at a claim and notice if it has an anomaly or two. For example, the software might notice that a customer is claiming too many treatments when there needs to be a reasonable time between the two. This anomaly can be flagged so that an investigator can look closer. Sometimes, it is not fraud but carelessness, so noticing the mistakes can help customers, too. Final thoughts New technologies can revolutionize how businesses operate, and AI is no different. Those in leadership positions in the insurance industry should seriously consider adding AI to their operations to keep up with the trends. Considering the advantages they bring, the effort can be worth it. Read Also: What Is the Typical Workman’s Comp Claim Process?

Best Practices For Visual Regression Testing On Cloud

Visual regression testing is the software testing process that is used to test your software application by visually finding any error or malfunctioning in the user experience. Visual regression testing ensures that an application or website maintains its intended look and behavior. It confirms the absence of any unplanned alterations to its visual design or functionality. This procedure entails comparing a reference version of the application or website and its current version, aiming to identify any visual disparities. Visual regression testing in a Cloud-based platform is the latest trend in the field of software testing and automation testing. It has various advantages, such as it increases the testing scope, costs less, and it increases testing flexibility. In this article, you will see the concepts of visual regression testing on the cloud, best practices for it, and many such things. What is Visual Regression Testing Visual regression testing evaluates the impact of code changes on the user experience by comparing screenshots before and after execution. It's also recognized as visual snapshot tests or visual testing, and its primary objective is to uphold visual consistency following updates. The Function Of The Visual Regression Testing Visual testing validates the suitability of an application's user interface in terms of its visual attributes. This quality assurance process aims to confirm the accurate display of content and data on the application's front end. In case you're not acquainted with the concept of Regression testing, its purpose is to ensure that any modifications made to the software do not disrupt any previously functioning elements. In the context of visuals, this testing guarantees that alterations to the software do not lead to style-related problems. The true capability of visual regression testing can be leveraged with Cloud-based AI-powered test orchestration and execution platforms like LambdaTest. It allows the running of visual testing across a large farm of 3000+ real device and OS combinations. This helps to ensure cross platforms compatibility on the visual appearance and interface of the software applications. Features Offered By The Cloud-Based Ai-Powered Test Orchestration And Execution Platform - Lambdatest For Robust Visual Regression Testing Are As Follows: This section discusses the features which are offered by the test orchestration and the execution platform.

This facilitates the analysis of essential UI components with due focus. Effortlessly install, set up, and execute the LambdaTest NPM package. This enables the direct implementation of the JS scriptsStorybook via our NPM CLI. Conduct regression testing, the visual ones for your mobile apps on genuine devices. Assure visual uniformity with precise pixel-to-pixel comparisons against your reference point, encompassing various screen sizes, resolutions, and layouts. Best Practices for Visual Regression Testing on Cloud Let us see the practices a tester must follow while performing visual regression testing on a cloud-based platform like LambdaTest. Following these practices during the test automation will make your software application visually more powerful and efficient. 1. Tool Selection: Choosing the appropriate tool to perform visual regression testing on the LambdaTest is one of the most important and essential steps in moving ahead of the testing process. Various parameters should be kept in mind during the tool selection for testing automation, such as the software type, compatibility aspects, resolution, etc. LambdaTest integrates with various tools like Selenium, Cypress, Playwright, and others, using which you can perform visual regression testing. 2. Consistent Environment: Never forget to create a conducive setup that will facilitate cloud-based visual regression testing. The interface provided by using these environments allows you to examine the visual outcomes and input received during the testing process. The testing team has the ability to pause the visual regression testing procedure and make the necessary corrections. The team conducting the testing should also maintain resource isolation for the environment. It aids in preventing any type of intervention during automation testing, which increases the effectiveness and productivity of cloud-based visual regression testing. 3. Isolation And External Factors: Remember that the isolated environment should not be affected by any external factors. They include network latency or fluctuations, system updates, or background processes running on the testing machine. These factors may lead to visual error and malfunctioning of the software application. External influences can potentially introduce visual errors and cause malfunctions in the software application. Ensuring a controlled environment by addressing the factors safeguards the accuracy of the testing results. All the screenshots and visual reports of the testing process will be saved in that specific folder. This will help to perform visual comparisons effectively. 4. Scriptless Test Cases Visual regression testing on the cloud platform using scriptless test cases is the best approach. Since numerous cloud-based AI tools are available, test automation can be utilized to develop test cases simultaneously. It is because the testing scope of a programmed test case is limited. But using AI technologies offered by LambdaTest for test case design opens up possibilities for the testing team to consistently cover the testing scope. It will perform visual testing against some test cases, and again, it will recreate the test cases according to the previous result and analysis. This practice will bring the best visual result for your software application. 5. Documentation Of Visual Test Cases Documentation is a very effective and important practice in any software testing process. In visual regression testing, you need to test and verify the components visually, and here it is important to mark down your observations, bugs, and analysis and work on them accordingly. For your visual regression tests performed in LambdaTest, you should create clear and succinct test cases and descriptions. You should also include comments or annotations to describe the aim and scope of your baselines and screenshots. Additionally, you should preserve and maintain your screenshots and baselines using a version control system or a cloud-based service. Sharing and communicating with the client will help you understand their demand and make the best possible result. 6. Updating The Baseline Updating the baseline is a very crucial step in the visual regression testing process when performed in LambdaTest. It consists of the practice of taking the feedback result and analyzing them. If the result is considerable, you can approve this update in the baseline. And if you think that it is not worth consideration, you can simply reject them. But you need to mention all these in the baseline. It is because this will help you in the future because you can see all your testing logs in the baseline. Mention the changes that were done intentionally, their reasons, and such things. It will also help all the team members have an overview of the changes that are going on in the software testing process. 6. Optimize Testing Coverage And Scope Always remember to prioritize the testing scope for each component, specifically when executing visual regression testing in cloud platforms like LambdaTest. The high-priority components must be paid more attention, and they should be executed with high precision. Use the concept of full-page and component-based screenshots to compare the changes visually by the testing team. Using this practice in visual regression testing will help achieve a better UI experience and enhance the testing results. You can use some advanced features like custom attributes. These attributes help find the elements separately during visual regression testing. Also, you can use the trigger events and DOM concept. These will help to perform the screenshot comparison effectively. 7. Performing Parallel Testing Apart from this, you can leverage parallel test execution in performing visual regression testing in LambdaTest. Executing parallel testing is what makes visual regression testing productive and effective, though, along with those other factors. 8. Learn From Failure It is the final practice that all testers must follow to perform visual regression testing on the cloud and during test automation. Learn from your previous failure. Document the mistakes that you have made previously. Write down the tool feedback and in which specific tool you got some issues performing the testing process. And learn from these highlights. Make your testing goal and work on your failures. This will bring the best result for your software application. Also, it will help in the overall development of the organization as well as the individual tester. You should follow These best practices while performing visual regression testing on the cloud. Conclusion Visual regression testing is mainly used to find any kind of visual malfunctioning and errors in the software. Visual inconsistency is one of the major reasons that lead to decreased number of users of a product. Some of the best practices that every testing team should follow to perform visual regression testing using the cloud are the selection of appropriate tools, using documentation, using AI-based test cases, etc. Various tools can be used to automate testing and perform visual regression testing on the cloud, such as LambdaTest. Hope you get an understanding of the best practices for visual regression testing using the cloud and their various aspects after reading this article.
