得らｎる。When the coil (7) is not connected to the drive circuit 0, the gap δ between the stator (6) and the rotor (1) is
Due to the difference between 1 and δ2, the attractive force between the NS pole of the loco (1) and the narrow part (6b) of the stator increases to the magnetic pole part (6a) of the stator.
) is stronger than the attraction force with the rotor (11 (7) N
This state will continue to be maintained as long as the S'IMu stator stops along the center line (X-axis) of the narrow part (6b) and is not energized. Next, in Fig. 1, for example, the N pole of the rotor (1) is on the minus X axis and the 8 poles are on the plus X axis, and when the driving circuit C1,) is energized in the positive direction of This magnetic field force is transmitted to the stator (6) via the iron core (9) and is applied to the magnetic pole part (6a) on the positive Y axis.
), if 8 poles are generated in the magnetic pole part (6a) on the N pole minus the X axis, the NS pole of the rotor (1) and the narrow part of the stator (
Since the attractive force between the 118 poles of the rotor (1) and the magnetic pole part (6a) of the stator is stronger than the attractive force of 6b), rotation starts counterclockwise. However, when the drive lever rotates by a predetermined angle of 01, the eave-like part (5a) of the drive lever hits the pin (4 mm) K on the upper plate and the rotor (1) Vi stops, and while the coil (7) is energized in the positive direction, this The state is maintained. And carp/
When the power to L (7) is cut off, the NS pole of the rotor (1) and the narrow part (6b) of the stator are attracted again, and the rotor (
The state of 1) in which the NS pole and the narrow part (6b) of the stator are opposed to each other is restored. Note that the rotation angle θ1 of the rotor (1) is 6.
If the setting is greater than 1/2 turn, not only will the return operation of the rotor (1) at the time of power cutoff become unstable, but also the rotational speed of the rotor (1) will slow down and the rotational output torque will decrease. An angle of one rotation or less is appropriately set. In addition, in FIG. 1, when a current in the opposite direction is applied to the coil (7) from the drive circuit (11), contrary to the above-mentioned example, S
The rotor (1) rotates in the clockwise direction by a predetermined angle θ22, and when the energization is cut off, the rotor (1) rotates clockwise by a predetermined angle θ22. Return to state. Therefore, the drive lever (5) is at a position rotated θ1 counterclockwise when the coil (7) is energized in the positive direction, rotated 022 clockwise when energized in the reverse direction, and θ1 when not energized. Three neutral positions of and 02 are obtained.
