Being the ecad system of the private medical equipment like the electromotive toothbrush which possesses the operational part which is driven with the drive which possesses the stator part via motion amplitude, the aforementioned system, the stator part the circuit where the average electric current which flows is measured (13), and motion amplitude and the relation to which the aforementioned operational part corresponds the information which is housed inside the private medical equipment which is attached (19), has the average current value which flows to the stator while operating of the device. The processor which uses the program which is housed (17), operational frequency is adjusted, the stator current value which correlates to the desire motion amplitude of the operational part is formed.固定子部品を有する駆動機構により運動振幅を通じて駆動される動作部分を有する電動歯ブラシのような個人医療機器の適応型システムであって、前記システムは、固定子部分を流れる平均電流を測定する回路(13)、及び装置の動作中に固定子に流れる平均電流値を前記動作部分の対応する運動振幅と関連付ける個人医療機器内に格納された情報(19)、を有する。格納されたプログラムを用いるプロセッサー(17)は、動作周波数を調整し、動作部分の所望運動振幅に相関する固定子電流値を生成する。
