A new energy vehicle motor with resonance defense function

Abstract

The invention relates to a new energy automobile motor with a resonance defense function. The motor comprises a support, a driving mechanism, a detection mechanism, a connection unit, a PLC and a fixed mechanism, wherein the driving mechanism, the detection mechanism, the connection unit, the PLC and the fixed mechanism are arranged on the support. The driving mechanism comprises an output shaft, a flange, a shaft sleeve, a front end shell, a back end shell, a fan, a substrate, a wiring box, a wiring box cover, a bolt, a stator and a rotor. The fixed mechanism comprises a driving unit, a base, a screw rod, a sleeve ring and a fixed block. The support is fixedly arranged on one side of the base. The detection mechanism is arranged on the substrate through the connection unit. When the motor resonates, resonant signals can be effectively detected; through the fixed mechanism, the fixed block is abutted against the substrate of the motor, so weight features of the motor are changed; fixed frequency of the motor is changed; the motor will not resonate under the current vibration frequency; and the normal work of the motor is ensured.

Description

technical field [0001] The invention relates to the field of new energy vehicle motors, in particular to a new energy vehicle motor with a resonance defense function. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to generate driving torque as a power source for electrical appliances or various machinery. Its main function is to convert electrical energy into mechanical energy. [0003] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. Including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc., and new energy vehicles generally drive the vehicle through a motor, while driving A series of vibrations will be generated during the process, which will also cause motor resonance under certain circumstances. [0004] When the motor resonates, it will shorten the wind...

AI Technical Summary

Problems solved by technology

[0004] When the motor resonates, it will shorten the winding insulation and bearing life, affect the normal lubrication of the sliding bearing, and the vibration force will promote the expansion of the insulation gap, causing the outside dust and moisture to invade it, resulting in a decrease in insulation resistance and an increase in leakage current, and even the formation of insulation. Accidents such as breakdown

In addition, the vibration of the motor will easily cause the water pipe of the cooler to vibrate and the welding point to vibrate, which will cause damage to the load machinery, reduce the precision of the workpiece, cause fatigue of all mechanical parts subjected to vibration, and loosen the anchor screws. Or broken, the motor will cause abnormal wear of carbon brushes and slip rings, and even serious brush fire will burn the collector ring insulation, and the motor will produce a lot of noise, which will cause harm to the motor and cause inconvenience to users.
