| description | To suppress drive sound which is generated when reverse voltage of a stepping motor is measured.SOLUTION: A motor control circuit comprises: a drive control signal generation unit 132 which generates a drive control signal Sd so that drive current approaches a target current value; a measurement timing specification unit 138 which specifies timing for measuring reverse voltage induced by a coil among a plurality of phases of coils of a stepping motor; a reverse voltage measurement unit 126 which measures reverse voltage in a state in which excitation to the coil of the stepping motor is continued in the specified timing; and a step out determination unit 136 which determines whether or not step out occurs in the stepping motor on the basis of the measurement value of the reverse voltage measurement unit 126.SELECTED DRAWING: Figure 4
【課題】ステッピングモータの逆起電圧を計測する際に生じる駆動音を抑制する。【解決手段】モータ制御回路は、駆動電流が目標電流値に近づくように駆動制御信号Ｓｄを生成する駆動制御信号生成部１３２と、ステッピングモータの複数相のコイルのうち、コイルに誘起される逆起電圧を計測するタイミングを特定する計測タイミング特定部１３８と、特定されたタイミングでステッピングモータのコイルへの励磁が継続された状態で逆起電圧を計測する逆起電圧計測部１２６と、逆起電圧計測部１２６の計測値に基づいてステッピングモータに脱調が発生しているか否かを判定する脱調判定部１３６と、を有する。【選択図】図４ |
