Embodiment Construction

[0026] The present disclosure will now be described with reference to several example embodiments. It should be understood that these embodiments are only described for the purpose of enabling those skilled in the art to better understand and thereby implement the present disclosure, rather than for the purpose of providing any limitation to the scope of the technical solutions of the present disclosure.

[0027] As used herein, the term "including" and variations thereof are to be read as open-ended terms meaning "including, but not limited to." The term "based on" is to be read as "based at least in part". The terms "one embodiment" and "an embodiment" should be understood to mean "at least one embodiment." The term "another embodiment" should be understood to mean "at least one other embodiment." The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below. Definitions of terms are consistent...

Abstract

Embodiments of the present disclosure provide a housing for a motor and a motor. The housing includes a body formed as a cylindrical structure extending in the axial direction; a plurality of heat dissipation ribs extending in the axial direction and arranged outside the body in the circumferential direction; at least one pair of ventilation windows, arranged to extend from the body respectively Both ends in the axial direction protrude radially outward so that a part of the plurality of fins can be arranged therebetween; and at least one air duct is arranged radially outside the fins in the axial direction, and is coupled to at least a pair of ventilation windows, so that the internal cooling air flow of the motor flows through the ventilation ducts. By arranging outwardly protruding ventilation windows at both ends of the body in the axial direction and ventilation ducts coupled with the ventilation windows and arranged radially outside, the heat dissipation ribs can also be arranged at the positions where the ventilation ducts are provided. This can effectively increase the heat dissipation area, thereby avoiding heat concentration, thereby improving the performance of the motor and prolonging the service life of the motor.

Description

technical field [0001] Embodiments of the present disclosure relate to an electric machine, and more particularly, to a housing for an electric machine. Background technique [0002] In the art, electrical machines can generally be classified into electric motors and generators in terms of power output. An electric motor is a device that converts electrical energy into mechanical energy. It uses the energized coil (that is, the stator winding) to generate a rotating magnetic field and acts on the rotor (such as a squirrel-cage closed aluminum frame) to form a magneto-electric rotational torque. A generator is a device that converts mechanical energy into electrical energy based on a similar principle. Motors generate a lot of heat when they are running. In order to avoid the adverse effect of heat accumulation on the operation of the motor, heat dissipation ribs are generally provided on the casing of the motor to increase the heat dissipation area to dissipate the heat g...
