Automatic elevator door

タイトルまたは説明

KNOWHOW smart door system is composed of special permanent magnet DC motor drives. This motor is self-developed by the company using the most advanced small module helical planetary gear, reducer transmission technology, and low noise, which completely overcome the noise problems of the usual permanent magnet DC motor speed reducer. This technology fills the blank of domestic related technologies, not only in the door areas, but also in other similar areas. It is a tremendous breakthrough. Door operator adopts permanent magnet DC motor drive: 1. Motor nearly enables quiet operation. 2. Great startup torque, and high efficiency of running. 3. Easier to control the speed. 4. No need of slow transmission. 5. DC power provided by the transformer drive voltage fluctuation range to allow a wider, more stable performance.
