摘要： A stepping motor having a rotor consisting of a permanent magnet magnetized such that N poles and S poles are alternately arranged in the hoop direction, stator cores with pole teeth oppositely disposed on the outer peripheral surface of the rotor, and a coil bobbin integrally containing the stator cores as the result of resin molding and being used for supporting a coil wound thereon. In the stepping motor, holes are formed in the coil bobbin, and the holes range from an outer wall of the coil bobbin to the outer peripheral surfaces of the pole teeth. In the stage of resin molding, the dies are brought into contact with the pole teeth by the utilization of the holes, thereby preventing the pole teeth from being declined in the radial direction, and securing a satisfactory rigidity of the coil bobbin.

摘要： Magnetic poles are arranged such that the N pole and the S pole alternate in a circumferential direction. Two N poles face each other with an interval of 180° therebetween, and two S poles face each other with an interval of 180° therebetween. Each of the magnetization center of a North magnetic pole and the magnetization center of a South magnetic pole is positionally shifted from the center position between the magnetization centers of two magnetic poles of the other polarity located on opposite sides of the North or South magnetic pole. The magnetization centers of the magnetic poles are disposed in such a manner as to be positionally shifted from geometric centerlines. Brushes are disposed along the respective geometric centerlines. The magnetization centers of two adjacent magnetic poles are positionally shifted toward or away from each other by the same shift angle α with respect to the respective geometric centerlines.

摘要： A rectilinear-motion actuator includes a motor, a reduction gear mechanism coupled with a motor shaft of the motor, and a rectilinear, reciprocative motion mechanism for converting a rotary motion of a last-stage gear of the reduction gear mechanism to a rectilinear, reciprocative motion. The last-stage gear has a pin provided thereon which is offset from its center of rotation. The rectilinear, reciprocative motion mechanism includes a movable plate having a slit and allowing the pin to move within the slit. The slit is arranged orthogonally to the axis of the motor shaft. The longitudinal center of the slit is located on a line in parallel with the motor shaft axis and passing through the center of the last-stage gear. The axis of reciprocative motion of the movable plate is offset from the line passing through the center of the last-stage gear in a direction away from the motor shaft.
