1.High efficiency: eliminate the loss ofexcitation system and improve efficiency.
2.Under low load condition is still efficient:permanent magnet motor efficiency whenoperating at full capacity is higher thanconventional asynchronous motor by morethan 9%, and the speed is reduced, theenergy efficiency remains unchanged.
3.Superdynamic torque: the maximum startingtorque of the permanent magnet synchronous motor is more than three timesthat of the torque, while the general asynchronous motor is only 1.6 times.
4.Control more stability: the corresponding timeof permanent magnet motor is <50ms, whichcan adjust the volume of air volume in a flashand make the air pressure really stable.
Permanent-magnet Motors Have Advantages Over Common Asynchronous Motors.
