The latest high-efficiency PM motor lifts are smaller in size than traditional gear lifts. The PM motors they carry are made of permanent magnets. They are small in size and light in weight. The transmission efficiency is increased by more than 30%, which can save energy and reduce CO2 emissions. quantity.


・PM motor introduction

PM motor, also known as "gearless permanent magnet synchronous motor".

Compared with traditional motors, they are smaller in size, less noisy, and more efficient. They consume only half of the power of traditional motors. They do not need to replace mechanical gear oil every year. They are more energy-saving and environmentally friendly. They use non-contact electromagnetic force to transmit power, which solves the problem of common traditional motors. The jitter problem during elevator startup and operation makes the elevator run more smoothly and comfortably.


・IM motor introduction

IM motor is also called "worm gear induction motor" or "traditional gear induction motor".

Traditional motors use gear transmission, which has low mechanical efficiency, high power consumption, high elevator operating costs, and additional oil must be added. The noise generated by gear meshing is also large. As the use time increases, there will be obvious vibration and noise.


・Host performance technology

The host adopts a gearless permanent magnet motor with vector VVVF synchronous drive technology, which is energy-saving and highly efficient. The host efficiency is greater than 90%. It is a dedicated microcomputer control system developed based on professional experience in elevators.
