Abstract

A stepping motor can prevent the careless inclining of terminal stand arranged at the periphery side of stepping motor. The stepping motor comprises the following components: a rotor which comprises a rotation shaft and a permanent magnet provided surrounding the periphery of rotation shaft; a stator which comprises a stator core that is vertical and formed with pole teeth; a driving coil which is arranged at the periphery side of the pole teeth; and the terminal stand which is arranged at the periphery side of stator. The brim part of stator core is arranged with a terminal stand holding part holding the terminal stand. The terminal stand holding part is formed with a first holding part supporting the bottom surface of terminal stand. The first holding part bends and extends in the direction from the brim part to the axial cord.

Description

technical field [0001] The invention relates to a stepping motor with a terminal block. Background technique [0002] In the past, in such Figure 16 In the small-sized stepping motor 60 shown in (a), the terminal block 62 formed of a resin material to which a plurality of terminal pins 61 is attached is provided on the outer peripheral side of the stepping motor 60 . The winding ends to which the coils 63 and 64 are connected are wound around the terminal pin 61 . [0003] A fitting hole 62a is formed in the center of the terminal block 62, and the holding parts 65b, 66b extending from the eaves 65a, 66a of the stator cores 65, 66 arranged back to back are fitted into the fitting hole 62a, and the The terminal block 62 is fixed. Figure 16 The top view of (b) and Figure 16 The front views of (c) respectively show the stator cores 65 and 66 in a state where the terminal block 62 is fixed (see Patent Document 1). [0004] In addition, among other conventional stepping moto...
