Abstract
A motor control device is electrically connected with a motor. The motor control device includes a controller and a driving circuit. The controller has a default value of time and generates a first driving signal and a second driving signal. The driving circuit includes a first switching element and a second switching element, the first switching element and the second switching element receive the first driving signal and the second driving signal respectively, and the first switching element and the second switching element are switched on or switched off alternately according to the first driving signal and the second driving signal respectively, so as to drive the motor to operate. The controller switches off the first switching element by the first driving signal the default value of time before the controller switches on the second switching element by the second driving signal, and the controller switches off the second switching element by the second driving signal the default value of time before the controller switches on the first switching element by the first driving signal.
