Abstract
A motor controlling device and a motor controlling method are provided. The motor controlling device includes a first sensor, a second sensor and a signal switching circuit. The signal switching circuit is electrically connected to the first and second sensors, respectively. The signal switching circuit is switched to the first sensor to output a first switching phase signal to drive a motor when the motor starts to operate. The signal switching circuit is switched to the second sensor to output a second switching phase signal to drive the motor when a predetermined switching condition is satisfied with a predetermined value during the motor operation.
