Description

Heat dissipation motor Technical Field The utility model relates to the technical field of motors, in particular to a heat dissipation motor. Background The motor can produce heat when using, if can not in time dispel the heat can influence the performance and the life-span of motor. Therefore, manufacturers can install a fan behind the motor to enhance the heat dissipation effect of the motor. The fan blows hot air on the motor radiator to enable fresh cold air to enter, so that heat is emitted. So that the motor can be maintained at normal operating temperature. The invention relates to the technical field of motors, in particular to a motor for automatically matching air quantity of a cooling fan, which comprises a motor body, a first blade, a second blade and an external power supply, wherein the motor body is provided with a main shaft and a fan cover, the first blade is fixedly connected with the main shaft and driven by the main shaft, the second blade and the first blade are coaxially and independently connected in a rotating manner, and the second blade is independently driven by the external power supply. The motor with the automatic air quantity matching function for the cooling fan can match the air quantity meeting the cooling requirement for the motor body according to the running state of the motor spindle, and meanwhile, the motor with the automatic air quantity matching function for the motor body according to the running environment of the motor can match the air quantity meeting the cooling requirement, so that the motor with the automatic air quantity matching function has a good cooling effect for the motor.
