Frequently Asked Questions

Can a permanent magnet synchronous motor be used as a generator?
Yes, it can. Due to its working principle, if it runs CW as a motor, it can run CCW as a generator. Note that a suitable controller with AFE function is required for generator operation.
Why can't I directly use a three-phase AC supply to start this motor?
Because the rotor has high inertia and the magnetic fields spin very fast; a static rotor cannot immediately synchronize with the fast-moving magnetic field without assistance.
Are there specific VFD requirements for this motor?
Yes, it requires a vector control VFD with specialized software, such as those from Siemens, Yaskawa, or ABB. Compatible series are available to match these motors.
How is the permanent magnet rotor protected from failure?
Each rotor undergoes corrosion resistance, high-temperature demagnetization, and consistency tests. The demagnetization index is strictly kept within 2%.
What are the typical applications for these motors?
These motors are primarily used in variable frequency speed applications, especially for high-speed industrial compressors, fans, and pumps.
What protection levels are available for harsh environments?
Standard protection is IP54, but higher levels like IP67 are optional for environments with significant oxidative corrosion or dust.
