ABSTRACT:
A synchronous motor includes a reduction gear train operatively connecting a rotor to an output shaft. A retaining member is rotatably mounted on and frictionally engages the first gear member of the reduction gear train for angular movement about the axis thereof, the first gear member being in mesh with a drive gear on the rotor. The retaining member has an abutment lug which is engageable with the engaging portion when the rotor is rotated in its reverse direction whereupon the engaging portion rebounds from the lug to cause the rotor to rotate in its normal direction. The shaft of the first gear member is parallel to the axis of rotation of the rotor and is disposed at a position angularly displaced about the axis of the rotor from a predetermined point of the rotor by an angle of 360.degree./P x n when said engaging portion is brought into engagement with the abutment lug wherein P is the number of the magnetic poles around said rotor and n is an integer (0, 1, 2, 3 . . . ).
