Motor control device, image forming apparatus and motor control method

摘要

Problem to be solved: to provide a motor control device capable of determining the cause of a failure.A bridge br formed by a first transistor Tr1 to a fourth transistor TR4 connected between the power source PW and ground GNDFirst resistor R1 andThe second resistor R2 andResistor R3 and resistorFourth resistor R4 andFifth resistor R5 andA first detecting portion for detecting a first level between the second resistor R2 and the third resistor R3 andA second detecting portion for detecting a second level between the fourth resistor R4 and the fifth resistor R5 andBridge brFirst resistor R1Second resistor R2A harness ha for supplying power by connecting the fourth resistor R4 and the motor Mt.First transistor Tr1The second transistorTransistor 3AndIf the fourth transistor TR4 is offBased on the first and second levelsDetermination of failure of motor MT and harness HA and.Diagram
