❓ Frequently Asked Questions
Can permanent magnet synchronous motors be used as generators?
Yes. They can work as generators due to their special operating principles. If it runs clockwise as a motor, it can run counter-clockwise as a generator. Note that generator operation requires a suitable motor controller with AFE (Active Front End) functionality.
Why can't I use a direct three-phase AC supply to start these motors?
Because the rotor has high inertia and the magnetic fields spin so fast that a static rotor cannot synchronize with the magnetic field instantly. A dedicated driver is required for startup.
What are the technical requirements for the VFD driver?
The driver should be a vector control VFD with specialized internal software. Compatible series include Siemens 6SE70, Yaskawa CR5, Mitsubishi A740, and B&R P84/P74. Our MH300 series VFD is specifically optimized for these motors.
How is the permanent magnet rotor protected from failure?
Each rotor undergoes rigorous testing, including corrosion resistance, consistency, high-temperature demagnetization, and linear demagnetization tests. The demagnetization index is strictly kept within 2%.
In what scenarios are these motors typically used?
These motors are primarily used in variable frequency speed applications where high efficiency, high speed, and compact power density are required, such as in advanced aeration blowers and high-speed compressors.
What are the benefits of the patented cooling structure?
The autonomous patented cooling structure allows for superior thermal management, ensuring the motor maintains peak efficiency during continuous S1 duty cycles while reducing noise and vibration levels.
