本発はパルスモータへの駆動パルスの周波数に応じて駆
動電圧を制御するＦ−Ｖ （周波数−電圧）変換回路を
付加したパルスモータ駆動装置に関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pulse motor drive device equipped with an F-V (frequency-voltage) conversion circuit that controls a drive voltage according to the frequency of drive pulses to a pulse motor. Regarding.
パルスモータ駆動装置のタイプには大別してパルスモー
タに一定の電流を付与して駆動する定電流駆動方式とパ
ルスモータに一定の電圧を付与して駆動する定電圧駆動
方式とが存する。The types of pulse motor drive devices are roughly divided into two types: a constant current drive method in which a pulse motor is driven by applying a constant current, and a constant voltage drive method in which a pulse motor is driven by applying a constant voltage.
定電圧駆動方式においてパルスモータは入力電気パルス
信号が入ってから次のステップまでの間にモータ回転子
は第４図の実線で示すように減衰振動を伴い、これによ
りモータの出力軸の回転が滑らかに行われないという欠
陥が存した。In a constant voltage drive system, the motor rotor undergoes damped vibration as shown by the solid line in Figure 4 between the input of the input electric pulse signal and the next step, and this causes the rotation of the motor's output shaft to slow down. There was a flaw in that it did not run smoothly.
定電流駆動方式においては、パルスモータの高速での立
ち上りトルク特性は、改善されるが、低速で振動チョッ
パ音が出るという問題が生じる。In the constant current drive method, the rise torque characteristics of the pulse motor at high speeds are improved, but a problem arises in that vibration chopper noise is produced at low speeds.
上記２方式のいづれも、モータの出力軸の振動という問
題を解決することができない。そこで本発明は上記欠陥
を除去したパルスモータ駆動装置を提供することを目的
とするものである。None of the above two methods can solve the problem of vibration of the output shaft of the motor. Therefore, an object of the present invention is to provide a pulse motor drive device that eliminates the above-mentioned defects.
本発明は、上記目的を達成するため、パルスモータの固
定子励磁巻線の各相に電気パルスを供給してパルスモー
タを駆動する装置において、前記電気パルスの周波数に
応じて前記固定子励磁巻線の各相への励磁電圧を変化せ
しめる手段を設けたものである。In order to achieve the above object, the present invention provides a device for driving a pulse motor by supplying electric pulses to each phase of a stator excitation winding of a pulse motor. A means is provided for changing the excitation voltage applied to each phase of the line.
従って、パルスモータに供給される電気パルスの周波数

て回転子の立ち上がり時間が短くなり、電気パルスの周
波数が低くなるとこれに応じて回転子の立ち上がり時間
が長くなる。これにより、回転子の１パルスごとの最初
の静止点と電気パルスの印加タイミングとが一致し、回
転子は、振動することなく円滑に回転する。Therefore, when the frequency of the electric pulses supplied to the pulse motor increases, the stator excitation voltage increases accordingly, shortening the rotor rise time, and when the frequency of the electric pulses decreases, the rotor excitation voltage increases accordingly. The rise time becomes longer. As a result, the first stationary point of the rotor for each pulse coincides with the application timing of the electric pulse, and the rotor rotates smoothly without vibration.

Reference numeral 4 denotes an F-V conversion circuit configured so that the output voltage signal changes according to the frequency of the input pulse, and the input terminal of this circuit is connected to the output terminal of the drive pulse generation circuit. 6 is a power amplifier circuit, which is connected to the power supply and the output end of the F-V conversion circuit. The power amplification circuit 6 amplifies the output voltage signal of the F-V conversion circuit 4 and supplies this amplified voltage to the pulse motor drive circuit 8. The drive circuit 8 supplies drive electric pulses to each phase of the stator winding of the pulse motor 10 based on the output voltage of the power amplifier circuit 6' and the output command pulse signal of the pulse distribution circuit 2, thereby driving the pulse motor 10. to drive.

すればよい。When the output pulse of the drive pulse generation circuit is input to the F-V conversion circuit 4, a voltage signal proportional to the frequency of the output pulse is output from the F-V conversion circuit 4, as shown in FIG. This output voltage is amplified by the power amplifier circuit 6 and supplied to the drive circuit 8. On the other hand, the output pulses of the drive pulse generation circuit are supplied to the pulse distribution circuit 2, which outputs rotation command pulses. This command pulse is supplied to the drive circuit 8. The drive circuit 8 applies electric pulses to each phase of the excitation winding of the stator of the pulse motor 10 based on the command pulse and the output excitation voltage of the power amplification circuit 6, thereby causing the pulse motor 1o to rotate. Starting, stopping, and steady rotation of the pulse motor 10 are defined by the frequency of the electric pulses applied to the stator. The rise time of the rotor of the pulse motor 10 is inversely proportional to the magnitude of the voltage of the electric pulse applied to the stator of the pulse motor. That is, in FIG. 4, if the predetermined rotation angle of the rotor of the pulse motor corresponding to one electric pulse is eO, the time t1 for the rotor to reach the angle θO by one electric pulse is
If you want to shorten the time t1, you can increase the excitation voltage to the pulse motor, and if you want to lengthen the time t1, you can decrease the excitation voltage.

とになり、パルスモータの回転子の振動が除去される。One electric pulse is applied to the pulse motor 10, and the rotor is supplied to the pulse motor in such a way that the rotor rises to an angle θ0, and when the inertia force reaches the first rest point angle θ1, the next electric pulse is applied. If the excitation voltage is set to the frequency of the electric pulse, the rotor of the pulse motor will rotate smoothly without vibration. The invention is based on this principle. For example, No. 2, as shown in FIG.
