Abstract

The invention provides a motor, belongs to the technical field of motors, and aims to solve the problems of poor heat dissipation and large influence of temperature rise on performance of the motor of the existing motor. The motor comprises a shell, a stator and a rotor component, wherein the stator and the rotor component are arranged in the shell; the rotor component comprises a rotating shaft and a winding arranged on the rotating shaft; the two ends of the rotating shaft protrude out of the shell; one end of the rotating shaft is provided with an outer flan blade; an inner fan blade is also arranged on the rotating shaft in a sleeving manner; the inner fan blade is positioned on one side of the winding and is arranged in the shell. The motor has the advantages of good heat dissipation effect, low motor temperature rise and superior performance.

Description

technical field [0001] The invention belongs to the technical field of motors, and relates to a motor. Background technique [0002] Motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. During the process of converting electric energy into kinetic energy, the winding group is easy to generate heat, which affects the conversion rate of energy. [0003] Chinese patent CN201639395U discloses a brushless generator field, including a stator, a rotor, an inner coil, a front cover, a front impeller and a rear cover, the front cover, the stator and the rear cover are sequentially assembled and connected as a whole, and the rotor is provided with a rotor shaft. The rotor shaft is supported by bearings on the front cover and the rear cover. The two ends of the rotor shaft pass through the front cover and the rear cover respectively. The part protruding from the front cover of the ro...
