Gearless motor, the latest innovation in elevator technology based on permanent magnet synchronous gearless elevator technology based on permanent magnet synchronous gearless machine is in great demand in the elevator industry because of following technical advantages:
The PMSM (Permanent Magent Synchronous Motor) use a rare earth permanent magnet with high magnetic flux density. In this system as a permanent magnetic flus is established, there is no need to release magnetizing current which in turn results in efficient control and energy saving. This invention allows the motor to have short length with large diameter and is compact in size and weight which allows installation in a small space. It is less noisy and provides unsurpassed smoothness and ride quality.
