Abstract
A motor control device controls the drive of a motor including a motor winding. The motor control device is provided with an energization control unit and a standstill determination unit. The energization control unit controls the energization of the motor winding in accordance with a detection value of a rotational position sensor that detects a rotational position of the motor. The standstill determination unit determines a standstill of the motor. When a standstill of the motor is detected, the energization control unit controls energization in a change pattern that is an energization pattern different from a preset regular pattern in accordance with the detection value of the rotational position sensor.
Claims11
A motor control device configured to control drive of a motor including a motor winding, the motor control device comprising:
- an energization control unit that is configured to control energization of the motor winding in accordance with a detection value of a rotational position sensor that is configured to detect a rotational position of the motor;
- and
- a standstill determination unit that is configured to determine a standstill of the motor, wherein
- the energization control unit is configured to, when the standstill of the motor is detected, control energization in a change pattern, which is an energization pattern different from a preset regular pattern, in accordance with the detection value of the rotational position sensor.
A motor control device comprising:
- a processor configured to
- control energization of a motor winding of a motor to drive of the motor in accordance with a detection value of a rotational position of the motor;
- determine whether a standstill, in which a torque of the motor drops, occurs in the motor;
- and
- in response to detection of the standstill, control energization in a change pattern, which is different from a preset regular pattern, in accordance with the detection value of the rotational position.
