ABSTRACT:
A dual purpose alternator starter for an automotive vehicle designed to be positioned between the engine and transmission. In place of the ring gear in a conventional drive train assembly, a pair of off set magnetically permeable discs are bolted to the power shaft. These discs form an annular channel between them. A plurality of rare earth permanent magnets are mounted on the inside face of one of the discs in the channel. On the opposite side of this disc, a set of ring shaped switch contact members are mounted. Positioned stationary to the engine and within the channel is a stationary ironless stator assembly having flat copper windings embedded in an insulation matrix. These windings alternately pass from the perimeter of the disc towards the interior of the disc as each winding forms a single pass around the ring shaped disc. A stationary brush assembly mounted to ride against the set of switch rings on the rotating discs conducts electrical current, when operated as a starter motor, through the ironless stator windings to produce a torque in one direction on the power shaft thus starting the internal combustion engine. When operated as an alternator, the magnetic flux from the permanent magnets cutting the windings of the stationary stator produces electrical current within the stator.
