Stepping motor and motorized valve using it

The stepping motor includes a stator 55 and a rotor 57 rotationally driven by the stator 55, and a detection rotor 47 detecting a rotation position of the rotor 57. The detection rotor 47 is rotatably disposed on a co-axial center L with the rotor 57 and rotationally driven via a rotation drive mech...

Beschreibung
Zusammenfassung:	The stepping motor includes a stator 55 and a rotor 57 rotationally driven by the stator 55, and a detection rotor 47 detecting a rotation position of the rotor 57. The detection rotor 47 is rotatably disposed on a co-axial center L with the rotor 57 and rotationally driven via a rotation drive mechanism between the rotor 57 and the detection rotor 47. The rotation drive mechanism has a drive play having a predetermined length or angle in the rotation direction.
