How Precision Motor Technologies and Applications Come Together

How Precision Motor Technologies and Applications Come Together

Selecting the right motor for your application can be a daunting and confusing task. Obviously, you should match the motor technology that best meets your performance and cost needs, but that approach has two challenges. First, it is not easy to define your application needs, because it often takes the knowledge and tools you might not have. Second, the number of permutations and combinations of motor technologies, motor configurations, and control approaches is significant and often takes years to understand.

Starting on September 29, in a three-day online Design News Focus on Fundamentals course, I will share with you what I have learned about four primary motor technologies, how they work, and how you can select the best one for your application, particularly precision motion applications. Each class is about 30 to 45 minutes and free, thanks to MICROMO, the sponsor of the course.

The topic of Day 1 will be brushless permanent magnet motors, Day 2 will be brush DC PM and piezoelectric motors, and Day 3 will be PM step motors. Each day, we will discuss in simple terms the essence of the technology that makes it a viable player in the precision motion market. We will identify the technology's advantages and disadvantages, and identify application characteristics that favor this technology as the best choice. We will look at actual examples that utilize the motor technology and explain the customer's challenge and the reasons behind the technology’s selection.

I once benefitted from these types of motor selection classes myself. When I founded my company, MTT, it was based on the knowledge that you cannot assess the proper use of electric motors without having some understanding of how the technology works. Conversely, just knowing the motor technology without having a sense of your fundamental needs leaves something to be desired, so MTT’s 30-year foundation relies on the talents of engineers who know the market with other team members who are conversant in motor and control technology.

Join me next week to listen, see, and ask questions. At the end of the short course, which will give you useful knowledge about the motor technologies without making you lost in the weeds of flux and windings and magnets, you will be in a good position to ask intelligent questions and make informed decisions when you need to select the best motor technology for your application.
