Episode #19
Getting in Sync with Permanent Magnet Motors
Permanent magnet motors are becoming increasingly common in industrial applications, offering higher efficiency, greater power density, and unique design flexibility. But how do they really differ from the induction motors we’ve relied on for decades? In this episode of VFD Vibes, Greg is joined by Yaskawa’s Keenan Wang to break down how permanent magnet motors work, their advantages and tradeoffs, and where they make the most sense. They also dive into what makes controlling a PM motor with a VFD different. From synchronization and vector control to motor tuning and encoder feedback, learn what it takes to get the best performance from a PM motor application. 02:03 Permanent Magnet Motors Explained 07:00 PM vs. Induction: Torque, Slip, and Overload 12:55 PM Motor Advantages and Tradeoffs 19:21 Where PM Motors Make Sense 22:58 Controlling PM Motors with a VFD 26:18 Vector Control, Sensorless, and Encoders 29:41 Setup, Tuning, and Common Pitfalls 34:40 Getting the Most from PM Motors Have a topic you want us to cover?
