ABSTRACT:
The present invention includes a rotary converter for converting direct current to altenating current. The rotary converter includes a rotor and a stator. The rotor includes a shaft, a commutator concentric with the shaft, and an armature core concentric with the shaft and adjacent the commutator, the core having slots in its outer circumference parallel to the axis of the shaft. At least one slip ring is mounted on the shaft adjacent the armature core. A first or direct current winding is electrically connected to the commutator and wound in a wave pattern through the armature cores slots. A second or alternating current winding is electrically connected to at least one slip ring and wound in a series of alternating clockwise and counterclockwise loops through the armature core slots. The rotary converter is particularly suitable for operation from a standard twelve volt battery to supply alternating current at a desired rating to electric tools and the like.
