Motor control device

The invention discloses a motor control device which comprises a central processor, a power driving circuit and a signal detection circuit. The central processor is connected with the power driving circuit. The power driving circuit drives the motor to work. The signal detection circuit is connected with the power driving circuit and the motor. The signal detection circuit is used for obtaining signals of the power driving circuit and the motor and transmitting the signals to the central processor. The central processor analyzes the signals and then controls the power driving circuit to drive the motor, and therefore the motor can be controlled. According to the motor control device, the motor can be controlled to stop rotating and rotate reversely in a protective mode when the motor exceeds the maximum load or an object entering a motor rotating protection area is detected, the central processor can control the motor, and therefore the motor has the position locking function or the unlocking function when stopping.
