Double-rocking-fan heat dissipation type motor based on self-vibration phenomenon

Abstract

The invention discloses a double-rocking-fan heat dissipation type motor based on a self-vibration phenomenon, and belongs to the field of motors. An elastic ball is driven to irregularly jump betweena heat conduction plate and a curved surface floating plate through the vibration generated during the operation of a motor body, and continuously impacts the curved surface floating plate, the curved surface floating plate continuously floats back and forth between a double-sided fan rocking frame and the heat conduction plate, so that the double-sided fan rocking frame continuously swings backand forth, air flow between the heat conduction plate and a shell is promoted, and heat between the heat conduction plate and the shell can be quickly dissipated to the outside through a dust-proof heat dissipation net. Therefore, compared with an existing air-cooling or water-cooling heat dissipation mode, the vibration phenomenon of the motor body is utilized to continuously assist the motor body in heat dissipation in the operation process of the motor body, and comprehensive and uniform heat dissipation of the motor body can be achieved without consuming extra operation cost.

Description

technical field [0001] The invention relates to the field of electric motors, more specifically, to a double fan cooling motor based on the self-vibration phenomenon. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy. It uses energized coils (that is, stator windings) to generate a rotating magnetic field and acts on the rotor to form a magnetoelectric force rotation torque. The motor is mainly composed of a stator and a rotor. The direction of the current-carrying wire in the magnetic field is related to the direction of the current and the direction of the magnetic field line (magnetic field direction). The working principle of the motor is that the magnetic field acts on the force of the current to make the motor rotate. As a typical rotating machine, motor vibration is a ubiquitous phenomenon, whether it is in a normal state or in a fault state. The magnitude of vibration has become a very important characteristic...

Problems solved by technology

[0003] The internal components of the motor are generally installed in the motor housing. During the operation of the motor, the internal friction of the motor will increase sharply. Almost all the internal friction of the motor is released in the form of heat. If the motor is not cooled effectively, the internal temperature of the motor will continue to increase If the temperature is too high, it will cause internal ablation or even breakdown and damage the motor

[0004] The heat dissipation methods of existing electric motors are mainly divided into air-cooled and water-cooled. The air-cooled type is installed with heat-dissipating blades at the end of the rotor shaft of the motor. During the operation of the motor, the rotor shaft drives the blades to rotate to form a heat-dissipating fan structure. The motor is ventilated to dissipate heat, and the air-cooled heat dissipation structure dissipates heat unevenly, and only has a good heat dissipation effect on the end of the motor, resulting in failures at the motor body and the front end of the motor due to poor heat dissipation; although the water-cooled heat dissipation structure dissipates heat evenly, The heat dissipation effect is also better than the air-cooled heat dissipation effect, but both the production cost and the operating cost are high
