The utility model relates to the field of electric control devices, in particular to a motor control circuit and a motor control system. The utility model provides a motor control circuit. The motor control circuit comprises an embedded processor sub-circuit, a motor driving sub-circuit and an angle sampling sub-circuit which are in signal connection in sequence. The embedded processor sub-circuit sends a motor control signal to the motor driving circuit, the motor driving circuit is used for driving motor commutation, three groups of sensors arranged at equal angles are arranged in the angle sampling sub-circuit, and the sensors are used for detecting pulse signals. And the angle sampling sub-circuit transmits the pulse signal to the embedded processor sub-circuit. The angle is controlled by calculating the initial position of the motor based on the pulse signal returned by the sensor of the motor, and the angle control device has the advantages of high control precision, flexible structural design, strong a
