To determine the time behavior of a cyclic motor process during use of an electrical hair removal device without using specific sensors; and determine more precisely the cutting activity of the hair removal device and/or the force applied onto the skin.SOLUTION: Parallel to measuring the motor current, the induced voltage of a motor 3 is measured and a timing property of the induced voltage is evaluated, where the duration of a time pattern in the induced voltage is analyzed as the timing property of the induced voltage, thereby determining the time behavior of a cyclic motor process during use of an electrical hair removal device 1 with a motor-driven hair cutting unit 2. The cutting activity of the electrical hair removal device 1 during use is determined based on the evaluated timing property of the induced voltage, and the force applied onto skin during use of the electrical hair removal device 1 is determined based on the measured motor current.SELECTED DRAWING: Figure 1 【課題】特定のセンサを使用せずに、電気除毛装置の使用中の周期的モータプロセスの時間挙動を決定する。また、除毛装置の切断活動および／又は皮膚上に加えられた力をより正確に決定する。【解決手段】モータ電流の測定に並行してモータ３の誘導電圧が測定され、誘導電圧のタイミング特性が評価され、誘導電圧における時間パターンの継続時間は誘導電圧のタイミング特性として分析されて、モータ駆動式毛切断ユニット２を備えた電気除毛装置１の使用中の周期的モータプロセスの時間挙動を決定する。電気除毛装置１の使用中の切断活動は、誘導電圧の評価されたタイミング特性に基づいて決定され、電気除毛装置１の使用中に皮膚上に加えられた力は、測定されたモータ電流に基づいて決定される。【選択図】図１
