Motor, motor driving system, electric push rod and electric speed reducer

Abstract

The invention discloses a motor, a motor driving system, an electric push rod and an electric speed reducer, relates to the technical field of motor equipment, and aims to solve the problems of axialplay, noise, abrasion and low efficiency of a motor-driven worm and gear structure. The main points of the technical scheme are that the motor comprises a shell which is provided with a front end shaft hole, wherein a bearing is arranged in the front end shaft hole; a rotor assembly which comprises a rotating shaft and a coil arranged around the telescopic rotating shaft, wherein one end of the rotating shaft is rotationally connected to the front end shaft hole through a bearing; a stator assembly which comprises a permanent magnet surrounding the rotating shaft assembly; and an anti-shiftingassembly which is used for limiting bidirectional axial movement of the rotating shaft. The invention provides the motor which is stable, low in noise, high in efficiency and suitable for a worm andgear structure and a motor driving structure.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a motor, a motor drive system, an electric push rod, and an electric reducer. Background technique [0002] With the rapid development of the kitchen electrical equipment industry, a large number of linear transmission telescopic devices are required to realize the automatic operation of kitchen equipment in various equipment of kitchen appliances. As the key structure of this type of equipment, worm gear motors directly affect the operation of equipment. situation. However, the worm gear motors currently used in the field of kitchen appliances are generally prone to jamming, resulting in the inability of stable and reliable operation of kitchen appliances. This phenomenon is especially common in range hoods, integrated stoves and other applications. Or the lift glass cannot be opened or closed. [0003] The main reason is that during the operation of the worm gear moto...

AI Technical Summary

Problems solved by technology

During the operation of the worm gear mechanism, the shaft is pushed and pulled in the axial direction, which easily causes the shaft to move in the axial direction; when the shaft is pulled outward, the end surface of the shaft sleeve on the shaft and the internal interference structure of the motor are in close contact with each other. If the motor is tight, there is friction between the surfaces inside the motor, which generates a large friction force. The motor needs to overcome this friction force to perform additional work, resulting in waste of energy consumption, and it is easy to cause wear inside the motor, which affects the accuracy of the motor; and when After the motor stops at this position, when the motor restarts, the motor needs to overcome the greater static friction between the surfaces and the resistance torque of its own startup, which may cause the motor to have too much resistance and fail to start, which will affect the kitchen appliances. normal operation of the equipment
