Abstract
Description
Technical Field
[0001] The invention relates to a cooling type electric motor. Background Art
[0002] An electric motor is a device that converts electrical energy into mechanical energy. It mainly includes an electromagnet winding or distributed stator winding for generating a magnetic field and a rotating armature or rotor. The energized coil is used to generate a rotating magnetic field and acts on the rotor to form a magneto-electrodynamic rotating torque. Existing electric motors generally use built-in rotating blades for induced draft cooling and heat dissipation. However, induced draft cooling generally introduces external airflow into the motor for cooling and heat dissipation. Although a filter is provided at one end of the motor for dust removal, a large amount of dust will still accumulate inside the motor after long-term use, which brings great inconvenience to subsequent cleaning and maintenance. For this reason, this patent proposes a new type of motor cooling structure, which can effectively avoid the accumulation of dust and other impurities inside the motor and improve the cleanliness of the motor.
