A motor with rotor cooling

Abstract

The invention relates to a novel rotor heat radiation motor comprising a shell, a stator winding, a stator, a rotor, a heat radiation fin, a motor shaft and a second connecting frame. The stator is connected with the internal wall of the shell through a first connecting frame. The stator winding is installed on the stator. The left and right ends of the shell are provided with process through holes. The motor shaft is arranged on the axis of the left and right process through holes of the shell. The shaft wall of the motor shaft is provided with a motor shaft shell. The left end of the motor shaft shell is provided with a front end fin. The right end of the motor shaft shell is provided with the heat radiation fin. The motor shaft shell is connected with the rotor through the second connecting frame. A cavity is formed by the rotor and the motor shaft shell. A cooling liquid tank is fixed on the internal wall of the rotor in the cavity by the motor shaft shell through a support. The motor shaft can reduce the temperature in the whole motor by using circulation flowing of the cooling liquid in the groove, and the work environment of the motor can be better improved through temperature measurement of the motor rotor by using processing of the 51 single-chip microcomputer minimum control system through adjusting the rotating speed of the fan.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor with rotor cooling. Background technique [0002] The motor is a mechanical device that realizes the conversion between mechanical energy and electrical energy and the transformation of electrical energy characteristics based on electromagnetic induction. It is inseparable from our daily life. Motors are electromechanical devices for the production and conversion of electrical energy, and are widely used in industry, agriculture, transportation, national defense and other fields. [0003] However, due to the higher and higher requirements for the working performance of the motor, the efficiency of power conversion is also getting higher and higher, so the loss generated inside the motor is very large, part of which is heat loss. Overheating inside the motor will damage the motor components and reduce the power quality. , which greatly increases the cost of motor maintenan...

[0003] However, due to the higher and higher requirements for the working performance of the motor, the efficiency of power conversion is also getting higher and higher, so the loss generated inside the motor is very large, part of which is heat loss. Overheating inside the motor will damage the motor components and reduce the power quality. , which greatly increases the cost of motor maintenance. Therefore, the measures to reduce the internal temperature of the motor must be continuously innovated, and the existing temperature monitoring and temperature adjustment technology should be fully utilized to improve the reliability of the motor operation.
