Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a brushless speed reduction plastic coated motor. Background Art

[0002] Electric motor, also known as motor for short, is a device that converts electrical energy into mechanical energy. It uses an energized coil (that is, stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel cage closed aluminum frame) to form a magnetic electrodynamic rotating torque. Electric motors are divided into DC motors and AC motors according to the power supply used. Most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (the speed of the motor stator magnetic field and the speed of the rotor rotation do not maintain synchronous speed). The electric motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines (magnetic field direction). The working principle of the electric motor is that the magnetic field acts on the force of the current, causing the motor to rotate.
