Abstract
A device for controlling a motor is provided. A type of a power component in a first drive circuit of the device is different from a type of a power component in a second drive circuit of the device. A loss of the power component in the first drive circuit is greater than a loss of the power component in the second drive circuit. When determining that a load of the motor is less than a preset load, a controller of the device controls the first drive circuit to stop working and controls the second drive circuit to start to work. When determining that the load of the motor is greater than or equal to the preset load, the controller controls both the first drive circuit and the second drive circuit to start to work.
