Abstract

The invention relates to a micromotor capable of extending voltage applicable scope, in particular to a micromotor capable of extending the voltage applicable scope of a mini-type small-power single-phase series motor or a permanent magnet DC motor. The micromotor capable of extending the voltage applicable scope comprises a motor, wherein the motor is provided with a voltage reducing device, and the voltage reducing device is connected with the motor in series. The voltage reducing device comprises a voltage reducing resistor, wherein the voltage reducing resistor is connected with the motor in series, and the voltage reducing resistor can divide the voltage when a power source is applied to the pressure reducing resistor and the motor, so that the scope of power supply voltage applied to the motor is extended and the steering sparkle of the motor is improved. By changing the resistance of the voltage reducing resistor, the motor can be applied to different voltage applicable scope and is convenient in installation and operation. The voltage reducing resistor is provided with a saw-toothed heat dissipating device, so that the micromotor can effectively dissipate the heat of the voltage reducing resistor, guarantees the use security of the voltage reducing resistor, and prolongs the service life of the voltage reducing resistor.

Description

technical field [0001] The present invention relates to a kind of micro motor, especially a kind of micro motor that expands the scope of application, specifically a kind of small and low power single-phase series excitation motor or permanent magnet direct current motor used to expand the voltage application range, belonging to the motor control technology field. Background technique [0002] With the continuous development of the circuit breaker industry, circuit breakers are becoming more and more miniaturized and intelligent. Motor voltage classification is getting finer and finer, which also puts forward higher requirements for the use of circuit breakers and motors. When manufacturing 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 needs of micro-hig...
