本発明はレコー ドプレーヤ、テープレコーダ等に使わ
れる周波数制御モータに関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to frequency controlled motors used in record players, tape recorders and the like.
従来例の構成とその問題点
近年音響機器の性能向上は目ざましいものかありレコー
ドプレーヤ、テープレコーダ等の回転装置を備えた機器
の回転精度の向上も同様である。Conventional Structures and Problems There has been a remarkable improvement in the performance of audio equipment in recent years, and the same is true for improvements in the rotation accuracy of equipment equipped with rotating devices, such as record players and tape recorders.
従ってこれらに用いられるモータも回転精度の向上が要
求されている。この解決の一手段として回転数を回転数
に同期した周波数で制御する周波数制御モータが普及し
つつある。Therefore, the motors used in these devices are also required to have improved rotational accuracy. As a means of solving this problem, frequency control motors that control the rotation speed at a frequency synchronized with the rotation speed are becoming popular.

である。第２図は従来の電圧制御モータであり１〜５で
示した部分は第１図に示しだモータと同じである。FIG. 1 is a sectional view showing an example of a conventional frequency control motor. 1 is a stator, 2 is a rotor, 3 is a case, 4 is a capstan for hanging a belt, 5 is a speed control circuit for controlling the number of rotations, and 6a and 6b are a pair of frequency generators. FIG. 2 shows a conventional voltage controlled motor, and the parts indicated by 1 to 5 are the same as the motor shown in FIG.
ここで第１図に示した従来のモータは第２図の電圧制御
モータに比較し生産数量が少なく、量産効果が小さい為
、周波数発生装置のコスト差以上にコスト高であった。Here, the conventional motor shown in FIG. 1 is produced in smaller quantities than the voltage-controlled motor shown in FIG. 2, and the mass production effect is small, so the cost is higher than the difference in cost of the frequency generator.
さらにケースの内部に周波数発生装置を組込んでいるの
で、モータ全体の高さＡ１か、狛２図の電圧制御モータ
の高さ八、に比較し大きく、機器の小型化に障害となっ
ていた。Furthermore, since the frequency generator is built into the case, the overall height of the motor is A1, which is larger than the height of the voltage-controlled motor shown in Figure 2, which is 8, which is an obstacle to miniaturizing the device. .
発明の目的
