Patent Images
1. A motor-driven appliance comprising:
- a motor; and
a control unit that is configured to control a drive output to the motor, the control unit comprising;
a state amount detection unit that is configured to detect a state amount indicating an operational state of the motor;
a fluctuation range derivation unit that is configured to derive a fluctuation range of fluctuation in the state amount, based on the state amount detected by the state amount detection unit;
a load presence/absence detection unit that is configured to detect whether the motor is in an unloaded state or in a loaded state, based on the fluctuation range derived by the fluctuation range derivation unit; and
a drive output unit that is configured to perform the drive output to the motor, based on the state detected by the load presence/absence detection unit.

Abstract
A motor-driven appliance includes a motor and a control unit that controls a drive output to the motor. The control unit detects a state amount indicating an operational state of the motor to derive a fluctuation range of fluctuation in the state amount. The control unit detects whether the motor is in an unloaded state or in a loaded state, based on the derived fluctuation range to perform the drive output to the motor, based on the detected result.
