PROBLEM TO BE SOLVED: To provide a motor controller small in size and capable of controlling a current value of a current supplied to a motor at a time of large current supply.SOLUTION: A motor controller includes: a power supply 10; a small current supply circuit 11 that changes a power supply voltage of the power supply 10 to a pulsed voltage and that supplies the pulsed voltage to a motor 8; and a large current supply circuit 12 that is connected in parallel to the small current supply circuit 11 to directly supply the power supply voltage to the motor 8. The small current supply circuit 11 includes: four FETs 3H, 3L, 4H, and 4L that constitute an H-bridge circuit; and a noise reduction capacitor 9. The large current circuit 12 includes: relay elements 1 and 2 for cutting off a current supplied from the power supply 10 to the motor 8; and a resistor 7 that adjusts a current value of the current supplied from the power supply 10 to the motor 8. |
