Gearless Machine
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 the following technical advantages:
The PMSM (Permanent Magnet Synchronous Motor) use a rare earth permanent magnet with high
magnetic flux density. In this system as permanent magnet is established, there is no need to release
magnetizing current which in turn results in efficient control and energy saving. The invention allows the
motor to have short length with large diameter and is compact in size and weight which allows
installation in small space, It is less noisy and provides unsurpassed smoothness and ride quality.
