Abstract

The invention provides a device for assisting in acceleration and deceleration of a permanent magnet synchronous motor by using an adjustable wind channel. The device is used for assisting in acceleration and deceleration of a permanent magnet synchronous motor. The adjustable wind channel consists of a main wind channel and branch wind channels. A wind channel fan is used for providing a wind source and the wind speed and the wind direction in the wind channel are adjusted by the adjusting wind channel, so that acceleration and deceleration during rotation of a rotating shaft of a motor are achieved, start and stop time of a permanent magnet synchronous motor are shortened, the working efficiency of a permanent magnet synchronous motor is increased, and energy loss is reduced. The devicecan be used for assisting in acceleration and deceleration of a permanent magnet synchronous motor.

Description

technical field [0001] The invention discloses an adjustable air duct auxiliary permanent magnet synchronous motor acceleration and deceleration device, which relates to the field of permanent magnet synchronous motor acceleration and deceleration. Background technique [0002] The permanent magnet synchronous motor uses permanent magnets to generate the magnetic field of the motor. It does not require excitation coils or excitation current. It has high efficiency and simple structure. It is a very good energy-saving motor. In the field of small and medium-capacity high-precision transmission, permanent magnet synchronous servo motors are widely used. However, when the existing large-scale permanent magnet synchronous motor is started and stopped, especially in the process from starting to working speed, it takes a long time, which reduces the work efficiency and wastes energy. Contents of the invention [0003] The purpose of the present invention is to provide the wind s...
