What are the advantages and disadvantages of permanent magnet motors compared to reluctance motors?
Reluctance motor operation principle is the rotor reluctance staggered change, stator through the switch control current break pull rotor reluctance small part, in the circumference of the order of on and off, drive the rotor rotation.
In terms of application scenarios, reluctance motors and permanent magnet motors are still not the same. Compared with permanent magnet motors, reluctance motors have higher noise, higher heat generation and lower power density. Because the torque pulsation is large, so the vibration is also large, the speed is generally difficult to do high (small seat speed can be a little higher).
The cost of excitation motors is lower than that of permanent magnet motors due to the lack of cage bars and permanent magnets.
