Hardware connection structure for permanent magnet synchronous motor

Abstract

The invention provides a hardware connection structure for a permanent magnet synchronous motor. The hardware connection structure comprises a permanent magnet synchronous motor, a connecting shaft and a gear, which are sequentially connected, wherein the gear is connected with a synchronous belt taking a steel wire rope as a strength layer and coated by a polyurethane or neoprene ring-shaped belt; and the inner circumference of the synchronous belt is dentiform and is meshed with a tooth-shaped belt wheel. The hardware connection structure omits additionally calculating reduction gear ratio and torque calculation, adopts a manner of directly connecting with the gear to control on-off of a freezer door, has the advantages of small size, easiness in mounting, simple structure, convenience in maintenance and simplicity in debugging, without needing additional calculation, and is lower in requirements on mounting staff.

Description

technical field [0001] The invention is applicable to the field of motors, and in particular relates to a hardware connection structure of a permanent magnet synchronous motor. Background technique [0002] With the continuous progress of society, cold storage can be used to solve the problems of vegetable preservation and transportation, but the question is what is used to keep the temperature in the cold storage? The answer is the door - the cold storage door. Today's cold storage doors mostly use AC asynchronous motors and DC brushless motors. These motors have many problems. Some motors cannot achieve adjustable speed, and some motors cannot achieve stability. If you want to realize these functions, you have to add a deceleration device to realize the switch action of the cold storage door. It has the disadvantages of complex structure, high failure rate, high maintenance cost, poor control accuracy, and low efficiency. It cannot meet the demand of high-end cold storage...
