Production process and production equipment of motor rotor for unmanned aerial vehicle

Abstract

According to the technical scheme, the production process of the motor rotor for the unmanned aerial vehicle comprises the following steps of: turning and forming a rotor shaft blank, and performing heat treatment through an electric melting furnace; painting the surface for later use; punching the rotor sheets into a rotor sheet group for later use; punching and forming the rotor sheet group andthe rotor shaft through the cooperation of a punching machine and a punching die; and testing the straightness of the rotor shaft of the rotor without leaving a factory. Compared with the prior art, the method disclosed by the invention has the beneficial effects that the production process is simple to operate, has lower technical requirements on workers, and is suitable for more working groups;the production efficiency is high, the quality of the produced motor rotor is good, the rotor shaft is subjected to oil immersion treatment, and after the rotor shaft for punching is lubricated by oil, an insulating paint layer on the surface is not easy to wear, so that the problem of electric leakage of the finished motor rotating shaft is avoided.

Description

Technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a production process and production equipment of a motor rotor for drones. Background technique [0002] Electric machinery (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. [0003] The motor is represented by the letter M in the circuit (the old standard is D). Its main function is to generate driving torque. As the power source for electrical appliances or various machinery, the generator is represented by the letter G in the circuit. Its main function is The role is to convert mechanical energy into electrical energy. [0004] Electromagnetic DC motors are widely used in drones; electromagnetic DC motors are composed of stator poles, rotor (armature), commutator (commonly known as commutator), brushes, casing, bearings, etc.; the rotor...

Problems solved by technology

[0004] Electromagnetic DC motors are widely used on drones; electromagnetic DC motors are composed of stator poles, rotors (armatures), commutators (commonly known as commutators), brushes, casings, bearings, etc.; the rotor at this stage is for To avoid the axial current generated by electromagnetic induction, a layer or even multiple layers of insulating paint will be coated on the outer surface of the motor shaft to prevent the generation of axial current during use and cause the motor to burn out; and the rotor at this stage The conventional production process is to manually stamp the motor shaft and rotor shaft directly through the traditional concave die. This method has low production efficiency, low degree of automation, and is prone to tilting, which will cause the insulating paint on the outer wall of the motor shaft to wear and damage the motor. performance is adversely affected
