Micromotors, collectively called "micromotors", refer to motors having a diameter of less than 160mm or a nominal power of less than 750 mW. The micro-motor is commonly used in a control system or a transmission mechanical load and is used for realizing the functions of detecting, analyzing, operating, amplifying, executing or converting electromechanical signals or energy and the like. The micro-motor is widely divided into 13 types, namely a direct current motor, an alternating current motor, a self-state angle motor, a stepping motor, a rotary transformer, a shaft angle encoder, an alternating current and direct current dual-purpose motor, a tachogenerator, an induction synchronizer, a linear motor, a piezoelectric motor, a motor unit, other special motors and the like. The micromotor integrates the high and new technical industries of multiple subjects such as motor, micro-electronics, power electronics, computer, automatic control, precision machinery, new material and the like, and particularly the application of the electronic technology and the new material technology promotes the technical progress of the micromotor

The micromotor can generate heat in the working process, the temperature of the motor is increased due to the fact that heat cannot be smoothly conducted out, the insulating materials adopted by the motor have working temperature ranges, and once the temperature is increased to exceed the highest working temperature of the materials, the motor needs to stop working and wait for temperature suppression. The existing method for inhibiting the working temperature of the motor is to add a fan heat dissipation mechanism, and exchange heat with the external cold air of the motor to achieve the purpose of cooling, or introduce a cooling medium to take away the heat to prevent the temperature of the motor from rising.
