Title:
ブラシレス直流モーターおよびその放熱装置
Document Type and Number:
Japanese Patent JP5264989
Kind Code:
B2
Abstract:
A brushless DC motor (100) and a radiating device thereof are provided. The brushless DC motor (100) includes a bracket (110), a stator (120) mounted on the bracket (110) and a rotor (130) rotating around the stator (120), the bracket (110) has an inner chamber (112), the rotor (130) has an opening (134) facing the inner chamber (112), wherein the radiating device includes a first radiator (142) which is provided in the inner chamber (112) of the bracket (110) and is thermal coupled with the stator (120) through the bracket (110) so as to send the heat out of the stator (120), and a turbine (144) which is provided within the opening (134) of the rotor (130) and is facing a first end (142a) of the first radiator (142) so as to discharge the heat sent from the first radiator (142) out of the motor (100) while the turbine (144) is rotating. The radiating device is simple in structure, and solves the problem of heat discharging of the large power brushless DC motor.
