Abstract
A double twin bobbin four pole motor is disclosed. The motor includes a first and second stack of magnetically conductive stacked laminations. The first stack includes a four pole central portion with a rotor opening and two pairs of spaced side legs, each spaced pair of side legs extending from opposite sides of the central portion generally in mirror image relationship with one another and terminating in an outer free extremity. Each of the stacked side legs of the stacked spaced pair of side legs have a combined predetermined outer cross sectional configuration. The second stack of laminations includes a pair of separate magnetically conductive stacked laminations for attachment to the outer free extremities of each pair of stacked side legs. Each of the second stack of laminations have a combined predetermined outer cross sectional configuration. At least one electrically conductive coil is positioned about the combined predetermined outer cross sectional configuration of one of each of the stacked side legs of the first stack of laminations or about each of the second stack of laminations. Each electrically conductive coil is preferably wound about an insulating bobbin which m…
