ABSTRACT:
A compound pulse motor for driving a printer or the like comprising an armature having linear magnetic poles and rotational magnetic poles and a stator having stationary linear magnetic poles and stationary rotational magnetic poles. In operation, the linear magnetic poles of the armature interact with the stationary linear magnetic poles of the stator to produce transverse motion of the armature. Furthermore, when excited, the rotational magnetic poles of the armature and the stationary rotational magnetic poles of the stator interact to produce rotational motion of the armature.
