Tooth tips, which fit over teeth and distal ends of fingers formed between slots in laminated disks making up a portion of a stator in a generator, facilitate slipping stator windings into the slots from a central opening in the laminated disks; cooperate with wedges to affix stator windings in the slots; and provide a slot gap between adjacent tooth tips, which is substantially smaller than the width of the slots, to reduce slot harmonics and improve performance of the generator.

A regulation system for a permanent magnet generator for generating electrical power and for supplying the electrical power to a load comprises a switching circuit connected between the permanent magnet generator and the load, the switching circuit being capable of regulating the electrical power being supplied to the load and a control circuit connected to the switching circuit, the control circuit for determining the amount of electrical power being supplied by the permanent magnet generator and for controlling operation of the switching circuit to regulate the electrical power being supplied to the load.

A programmed PWM controller for controlling an inverter is provided which includes memory means for storing a plurality of drive data words representing a pulsewidth modulation sequence, each drive data word including a driveword and a drivetime word, the drivewords being used to operate the inverter; first digital means for selectively retrieving each of the plurality of drive data words from the memory means according to the pulsewidth modulation sequence in response to a next drive data word request signal; and second digital means governed by the drivetime word for generating the next drive data word request signal.
