Abstract

PURPOSE:To obtain a rotating-direction control apparatus of a synchronous motor, in which the rotating directions can be regulated and the forward and reverse rotations can be switched arbitrarily, by making DC flow in the direction corresponding to the desired rotating direction to a motor driving coil before operation. CONSTITUTION:A rotating direction regulating arm 6a for the counterclockwise direction and a rotating direction regulating arm 6b for the clockwise direction are pivoted on a shaft 15. Magnets 7a and 7b are attached to the arms 6a and 6b through window parts 10a and 10b, which are provided in a gear case 9 so as to face a motor driving coil 8. When a switch S1 is turned before a switch S3 is turned ON, the tip of the arm 6a is protruded into the rotating path of a stopper 5, and the tip 22 of the arm 6b is moved out of the rotating path of the stopper 5. Thereafter, when the switch S1 is turned OFF and the switch S3 is turned ON, the rotation of the synchronous motor in the clockwise direction is restricted with the arm 6a, and the rotation of the motor in the counterclockwise direction is started positively.

Rotation direction control of the present invention as described in the detailed description of the invention! The Il device operates by supplying DC power in the direction corresponding to the desired rotation direction to the motor drive coil, so that the counterclockwise arm and clockwise arm are connected to the first and second magnets and the motor drive coil. One arm protrudes into the rotation path of the stopper due to the action of the generated magnetic field, and the other arm protrudes into the rotation path of the stopper by switching the direct current direction, so rotation in one direction or rotation direction is specified. It is possible to operate reliably in any selected direction, which was impossible with conventional synchronous motors. Therefore, it can be used in applications that until now required forward and reverse rotation and had to use expensive motors such as stepping motors. It becomes possible to use an inexpensive synchronous motor.
