The invention relates to a convenient-for-heat radiation new energy automobile motor having the cleaning function. The motor comprises a casing and a rotation shaft, wherein two ends of the rotation shaft are provided with multiple cleaning mechanisms, the casing is internally provided with two ventilation mechanisms, the ventilation mechanisms comprise ventilation pipes, filters, blocking plates,moving rods, rotary tables, transmission assemblies and two touch assemblies, the transmission assemblies comprise first cylinders, first pistons, curved plates, connection rods, gas pipes, second cylinders and second pistons, and the cleaning mechanisms comprise cleaning plates, first springs, two positioning units and multiple hairbrushes. The new energy automobile motor is advantaged in that the filters are prevented from absorbing dusts through the ventilation mechanisms when the motor is idle, the blocking plates are automatically moved away after the motor starts, heat radiation and ventilation of the ventilation pipes are convenient, in the high speed rotation process of the rotation shaft, the cleaning plates are away from the rotation shaft in the rotation process, the surface ofthe filters is cleaned through the airbrushes, the heat radiation and ventilation effects of the casing are further guaranteed, and practicality of the motor is improved.
