This paper describes the characteristics of a pulse motor with a new viscous damper which prevents the pulse motor from hunting. The damper is composed of two parts placed concentrically, one is a rotatable and has a soft iron armature, which is supported on a shaft by ball bearings and has a plurality of spaced poles, and a damper case fixed on the shaft having a suitable gap around the armature which is filled up with silicone oil, and the other is of stationary field structure with an excite coil and as many poles as the armatures. Using the damper, the writer has obtained a pulse motor which is usable at +5° to +85°C temperature, 0 to 500 pps frequency and maximum 700g-cm pull out torque without hunting.
