Sweg Motor
Comparing with the standard AC motors, the permanent magnet motor can achieve IE4 / IE5 Super Premium Efficiency level, the max efficiency can be 97%. Instead of combination of traditional AC motor and speed reduce device, it can avoid the maintenance of the speed reduce device, and also avoid mechanical power transmission losses caused by it.
