Abstract
A motor application apparatus is provided. The apparatus includes a motor, a cooling device, a temperature sensor to detect a temperature of the motor, a microcontroller configured to output a controlling signal to control rotation of the motor and acquire a supply current and a rotation speed of the motor in real time. When the temperature of the motor is higher than a predetermined value or the microcontroller determines that the motor is in a high temperature operation state according to the current and the rotation speed, the microcontroller outputs a protection signal to start the cooling device.
