Abstract: A motor controller includes a motor, an encoder, and a control circuit. The motor drives a target object to be controlled. The encoder outputs a pulse signal synchronously with rotation of the motor. The control circuit rotates the motor based on a count value of the pulse signal. The control circuit switches to a sleep mode when making sure that a rotation position of the motor is stable after finishing rotating the motor or when a predetermined time necessary for the rotation position of the motor to be stable elapses after finishing rotating the motor. When a change in the pulse signal during a period of time where the control circuit is in the sleep mode is not smaller than a predetermined amount, the control circuit performs a learning process to learn a reference position of the motor when returning to a wakeup mode from the sleep mode.

In an angular section where the output voltage from an inverter device is linearly approximated with the zero cross point as the center thereof, a PWM generator in the inverter device changes either the time interval between the centers of PWM ON pulses or the time interval between the centers of PWM OFF pulses depending on the inverter operation state. An electric vehicle is equipped with the inverter device, which drives a motor.
