[0003] Joint robot, especially the joint part of humanoid robot, often uses frameless torque motor as power source. In frameless torque motor, the stator is one of the key components of the motor, and the stator is usually composed of core and winding. The core is composed of silicon steel sheet, so as to reduce eddy current and hysteresis loss. The winding is wound by insulated wire and arranged on the core according to certain rules to form electromagnetic field.

This is because high temperature will increase various losses of motor, such as iron loss and copper loss, which will be converted into heat, further increasing the temperature of motor stator, and the efficiency reduction means that the motor needs to consume more electric energy under the same output power, thereby increasing energy consumption.
