【考案の詳細な説明】
本考案は時計などに用いられるモータの駆動回路に関す
るもので、消費電力を削減することを目的とするもので
ある。[Detailed Description of the Invention] The present invention relates to a drive circuit for a motor used in a watch or the like, and its purpose is to reduce power consumption.
以下本考案の一実施例を図面に基づいて説明する。An embodiment of the present invention will be described below based on the drawings.
第１図においてパルス発生回路ＣＬの端子ａからは第２
図Ａのパルスが発生し、端子すからは上記パルスより十
分長い周期で第２図Ｂの制御パルスが発生するように設
定しである。In FIG. 1, the second
The pulse shown in FIG. 2A is generated, and the terminal is set so that the control pulse shown in FIG. 2B is generated at a sufficiently longer period than the above pulse.
制御回路を構成するスイッチング回路Ｓは上記制御パル
スによって閉じ、通常は開いている。The switching circuit S constituting the control circuit is closed by the control pulse and is normally open.
したがって通常は、第２図ＡのパルスがモータＭのコイ
ルＬの一端に供給されるとともにインバータ■によって
レベル回転されてコイルの他端に供給されロータＲが回
転する。Therefore, normally, the pulses shown in FIG. 2A are supplied to one end of the coil L of the motor M, level-rotated by the inverter (2), and supplied to the other end of the coil, thereby causing the rotor R to rotate.
そしてロータＲに十分な慣性が与えられたところで第２
図Ｂの制御パルスが発生してスイッチング回路Ｓが閉じ
る。Then, when sufficient inertia is given to the rotor R, the second
The control pulse shown in Figure B is generated and the switching circuit S is closed.
したがってコイルＬに供給される駆動パルスが第２図Ｃ
のように間引きされる。Therefore, the drive pulse supplied to the coil L is
It is thinned out like this.
このときロータＲは十分な慣性を持って回転しているた
め、駆動パルスが間引かれてもその回転速度は一定に保
持される。At this time, since the rotor R is rotating with sufficient inertia, its rotational speed is maintained constant even if the drive pulses are thinned out.
以上のように本考案によれば、駆動パルスを間引きする
ためその分だけ消費電力を節減でき、しかもロータは一
定速度で回転し続けるものである。As described above, according to the present invention, since the drive pulses are thinned out, power consumption can be reduced accordingly, and the rotor continues to rotate at a constant speed.
