Title:
OSCILLATING STEP MOTOR
Document Type and Number:
Japanese Patent JP2014163790
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that an oscillating step motor using a rotation control member according to prior arts is difficult to miniaturize and has poor accuracy in positioning.SOLUTION: A tabular nonmagnetic member is used as a rotation control member, so that a laminate structure of the rotation control member and a stator is allowed and the reduction in size and thickness can be achieved. A gear fall prevention part is provided to improve assemblability, and therefore, stabilization of an attachment posture improves accuracy in positioning and the reduction of power consumption can be achieved. Further, a fixing part of the rotation control member is installed in an area other than an area formed between the stator and a coil to improve the accuracy in attachment in small size.
