Description
Technical Field
The utility model relates to an air-cooled motor shell section bar.
Background
An electric motor is a device that converts electrical energy into mechanical energy. The electromagnetic power generator utilizes an electrified coil (namely a stator winding) to generate a rotating magnetic field and acts on a rotor (such as a squirrel-cage closed aluminum frame) to form magnetoelectric power rotating torque. The motors are divided into direct current motors and alternating current motors according to different power supplies, most of the motors in the power system are alternating current motors, and can be synchronous motors or asynchronous motors (the rotating speed of a stator magnetic field of the motor is different from the rotating speed of a rotor to keep synchronous speed). The motor mainly comprises a stator and a rotor, and the direction of the forced movement of the electrified conducting wire in a magnetic field is related to the current direction and the direction of a magnetic induction line (magnetic field direction). The working principle of the motor is that the magnetic field exerts force on current to rotate the motor. The air-cooled motor is a device which is widely used for providing power for equipment in various large and small enterprises in China, the air-cooled motor is a product which is of the same type all the time, almost all the same appearance is on a circle made of an iron plate with the thickness of 0.5 cm, and a heat dissipation iron sheet with the height of 2 cm is welded.
