Abstract
A starter cutoff control apparatus and method for a starter/generator used on an engine includes a circuit for detecting starter/generator armature current during an engine start operation, comparing the armature current to an armature current setpoint to produce an error signal; using the error signal to produce a field weakening control signal; and a circuit for producing a starter cutoff signal as a function of the field weakening control signal.
