featureadvantage
high efficiencyBy adopting rare earth permanent magnet material, full load efficiency of the motor is up 3%.
By adopting high-speed direct drive and removing step-up gearbox, the system efficiency is up about 5%~7%.
By adopting various frequency speed regulating technique the efficiency value is 5%~30% higher compared with three-phase asynchronous motor under partial load operation.
Small size and high power densityPermanent magnet motor features high efficiency and low loss and smaller size compared with three-phase asynchronous motor under the same cooling condition. It removes step-up gearbox by adopting high-speed direct drive structure. The power factor of motor will not lower with pole number increasing, making multi-pole easy.
High reliabilityWith no step-up gearbox, rotor conducting bar, coil, cast aluminium and end ring of the induction motor, the high-speed permanent magnet motor is operating more stably and reliably.
Direct driveThere’ no need for step-up gearbox by adopting high-speed direct drive structure. It’s of simple structure and easy maintenance.
