Problems solved by technology

Especially in the manufacture of high-voltage micro-series motors greater than 380V, it is often encountered that the wire diameter is too thin, the winding is easy to break and damage, and the motor commutation sparks are not easy to control. It is difficult for ordinary winding equipment to meet high-voltage micro-series motors. The requirements of motor winding parameters enable a motor of one voltage level to operate normally under multiple voltage levels

Abstract

The invention discloses a micro-motor of a breaker applicable for multiple voltage ranges. The micro-motor comprises a motor main body, wherein the motor main body is connected with a variable resistor device in series; and moreover the motor main body is connected with a voltmeter in parallel; the variable resistor device comprises a variable resistor; a heat radiation member is adhered outside the variable resistor by using a heat conduction insulation epoxy adhesive. According to the micro-motor of the breaker applicable for multiple voltage ranges, the partial voltage principle of the resistor in a series circuit is adopted, the variable resistor device is used for reducing a power supply voltage of the motor main body, and the redundant heat is radiated more easily by the heat radiation member. According to different voltages, the resistance of the variable resistor is adjusted, so that the voltage displayed on the voltmeter is a rated voltage of the motor, so that a high voltage micro-motor is applicable for wider voltage ranges; and moreover the micro-motor is applicable for various high voltages due to different resistances of the variable resistor, so that the voltage grade types of the motor are reduced greatly.

Description

technical field [0001] The invention relates to a micromotor for a circuit breaker, in particular to a high-voltage micromotor for a circuit breaker suitable for various voltage ranges. Background technique [0002] With the continuous development of the circuit breaker industry, circuit breakers are becoming more and more miniaturized and intelligent. The division of motor voltage levels is getting finer and finer. This also puts forward higher requirements for circuit breaker motors. Especially in the manufacture of high-voltage micro-series motors greater than 380V, it is often encountered that the wire diameter is too thin, the winding is easy to break and damage, and the motor commutation sparks are not easy to control. It is difficult for ordinary winding equipment to meet the requirements of high-voltage micro-series motors. The requirements of motor winding parameters enable a motor of one voltage level to operate normally under multiple voltage levels. Contents ...
