Air-cooled type motor for electric vehicle

Abstract

The invention provides an air-cooled type motor for an electric vehicle. The air-cooled type motor comprises a motor base (1) and a stator (2), wherein a continuous spiral groove (4) is arranged on the inner wall of the motor base (1), one end of the spiral groove (4) is communicated with an air inlet (3) and the other end of the spiral groove is communicated with an air outlet (5), the air inlet(3) and the air outlet (5) are respectively arranged at the top and the bottom of the motor base (1) and are communicated with the exterior of the motor base (1), the axis of the air inlet (3) has anangle of 0-60 degrees with the horizontal direction. The air-cooled type motor for the electric vehicle provided by the invention utilizes air flow generated by vehicle traveling to form natural ventilation, thus the energy consumption and the use cost can be obviously reduced; and meanwhile, a spiral air channel is adopted, thus the wind path route can be obviously increased, the effect of heat dissipation can be improved, the normal operation of the motor can be ensured and the service life of the motor can be increased.

Description

technical field [0001] The invention relates to an air-cooled motor, in particular to an air-cooled motor for an electric vehicle, belonging to the technical field of automobiles. Background technique [0002] Electric vehicles are new energy green and environment-friendly vehicles that have been actively promoted in recent years. The electric energy used by electric vehicles is a renewable resource that can be obtained from a variety of energy sources, such as coal, nuclear energy, hydraulic power, wind power, light, heat, etc., and can replace the precious and increasingly depleted petroleum resources. The cost of electricity is low, and it can make full use of the surplus electricity when the electricity consumption is low at night to charge, so that the power generation equipment can be fully utilized day and night, further reducing the cost of electricity energy. Compared with traditional fuel vehicles, electric vehicles do not emit pollutants such as carbon dioxide an...
