１・・・ロータ、５・・・駆動軸、２・・・シールド板
、９゜９′・・・コイル、７・・・ステータコア。Fig. 1 is a sectional view showing the structure of a conventionally well-known PM type 4-phase step motor, Fig. 2 is its equinodal circuit, Fig. 3 is an electrical wiring diagram showing the drive circuit of a general step motor, and Fig. 4 The figure is a state transition diagram showing the excitation state in the case of the conventional two-phase excitation force type, and Figure 5 is a state diagram showing the excitation state in the case of the conventional two-phase excitation force type. Figure 5 shows the rotation of the shaft measured by the motor operation of 8 steps of forward and reverse rotation using the excitation method shown in Figure 4. A conventional characteristic diagram, Figure 6, is a conventional characteristic diagram in which excitation is stopped only during stoppage and actuated at every step, similar to Figure 5, and Figure 7 is a conventional characteristic diagram.
The figure is a sectional view showing one embodiment of the motor of the present invention, and FIG. 8 is a characteristic diagram of the structure shown in FIG. 7 measured under the same conditions as FIG. 6. 1... Rotor, 5... Drive shaft, 2... Shield plate, 9°9'... Coil, 7... Stator core.
