Brushless DC motor uses semiconductor switching devices to realize electronic commutation, that is, electronic switching devices are used to replace the traditional contact commutator and brush.

The stator winding of motor is usually made into three-phase symmetrical star connection, which is very similar to three-phase asynchronous motor. The rotor of the motor is attached with

1. Function:DC motor is used for indoor fan and outdoor fan of full DC variable frequency air conditioner. Its function and installation position are the same as PG motor of indoor unit and outdoor fan of outdoor

With the continuous improvement of production modernization and the continuous increase of people's consumption of household appliances, automobiles, etc., the market demand for motors will also be growing.

(1) Before disassembly, use compressed air to blow out the dust on the motor surface and wipe it clean.(2) Select the working place for motor disassembly and clean up the site environment.

The main parameters to be referred to in the selection of brushless DC motor are as follows:Maximum torque: It can be obtained by adding the load torque, moment of inertia and friction.

advantage:a) The speed change is stable and almost no vibration is felt;b) Low temperature rise and good reliability;c) The price is low, so it is selected by many manufacturers.

Generally, DC motors have the same working principle and application characteristics, but their composition is different. In addition to the motor itself, the former also has a commutation circuit

1. The gear reducer motor is manufactured according to the national professional standard ZBJ19004 production technical requirements;

Correct installation and maintenance of planetary gear reducer motor is the key to the normal operation of planetary gear reducer motor. Therefore, when you install the planetary gear reducer motor
