FAQ
1. Can performanent magnet synchronous motors be used as generator? 
No. Permanent magnet synchronous motors are absolutely different from generator. Only AC motors output speed and torque to drive electric devices. 
 
2. Why three-phase AC motors cannot supply voltage to start permanent magnet synchronous motors? 
Becuase of the big innertia of the rotor and of the magnetic field the static rotor has no way to spin fast enough. 
 
3. Any special technical request on this motor's VFD driver? Do you have such driver? 
Permanent magnet synchronous motor's driver should be vector control VFD with special inner software, such as Siemens 6SE70 series, Yakawa CR5 series, ABB ACS800 series, Mitsubishi A740 series, B&R P84 and P74 series, etc.. Yes, our MH300 series VFD matches with this motor. 
 
4. Is there any protective measures to defend permanent magnet rotors from failure? 
Yes, each permanent magnet rotor passes corrossion resistance, consistency, high temperature demagnetization test, linear demagnetization test, etc. Its demagnetization index is within 2%. If the working environment is highly corrosive, kindly advise for higher protection level. 
 
5. What is this permanent magnet synchronous motor normally used for? 
This permanent magnet synchronous motor is normally used in variable frequency speed situations.
