ABSTRACT:
Low cost multi-pole motor constructions and related methods of manufacture are disclosed. The economic advantages inherent in the construction and manufacture of C-frame motors, including modified and improved C-frame or twin bobbin motor constructions, have been applied to a variety of different kinds of motors including two pole, four pole and six pole permanent split capacitor motors; four pole, six pole, and eight pole shaded pole motors; stepper motors; multi-pole switched reluctance motors including two pole, four pole, six pole, and other multi-pole switched reluctance motors; as well as various other types of multi-pole motors. Such modified and improved C-frame motor constructions include the mounting of electrically conductive coils on at least one pair of adjacent and spaced side legs on one or both sides of a multi-pole central portion. Related methods for manufacturing laminations used in such motors from an elongated strip of material are also disclosed.
