Document Type and Number:
Japanese Patent JP2019103319
Kind Code:
A
Abstract:
To prevent a component operating normally by electromotive force of a motor from being damaged even when a power supply (operating power) is stopped.SOLUTION: When supply of operating power is stopped, a power generation unit generates operating power on the basis of an electromotive force generated by a motor. A control unit operates on the basis of the operating power generated by the power generation unit and controls a rotation of the motor to suppress the generation of electromotive force. Thus, even if power supply (operating power) is stopped, the electromotive force of the motor can operate normally to prevent a component from being damaged.SELECTED DRAWING: Figure 4
