Problems solved by technology

When the stator is energized and generates a rotating magnetic field, the stator will generate heat. If the heat of the stator is not dissipated in time, heat will accumulate, which will affect the working performance of the stator, and then affect the performance of the motor.
[0003] In the process of realizing the present invention, the inventor of the present invention found that at present, most of the motors are cooled by air cooling, that is, a fan is added to the motor, and the motor is driven by the fan to drive air circulation. For heat dissipation, but this method will greatly affect the size of the actuator, and the cost is high

Abstract

The embodiment of the invention relates to the technical field of robots, in particular to an actuator, a machine body and a robot. The actuator includes a housing, a stator, an outer rotor and a driving plate; the housing is provided with a cup joint part, and heat conduction is carried out between the cup joint part and the housing; the stator is arranged outside the cup joint part in a sleevingmanner, and heat conduction is carried out between the stator and the cup joint part; the outer rotor is rotatably connected to the cup joint part and covers the stator; and the driving plate is fixed to the housing and is electrically connected to the stator. In the above manner, the embodiment realizes natural heat dissipation of the actuator, a fan does not required to be arranged, the housingis directly used for heat dissipation, and the cost is lower.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of robots, in particular to an actuator, a mechanical trunk and a robot. Background technique [0002] The actuator usually includes a drive unit and a motor. The drive unit is connected to the motor and is used to input current to the stator of the motor. After the stator is energized, a rotating magnetic field is generated and acts on the rotor of the motor to form a magnetoelectric power rotation torque, thereby driving the rotor to rotate and realizing the motor The rotation output. When the stator is energized and generates a rotating magnetic field, the stator will generate heat. If the heat of the stator is not dissipated in time, heat will accumulate, which will affect the working performance of the stator and the performance of the motor. [0003] In the process of realizing the present invention, the inventor of the present invention found that at present, most of the heat dissi...
