ABSTRACT:
The problem of excess size and weight resulting from the use of current sensors in a VSCF start system (10) is solved by a motor control (22) which utilizes a current estimator (68) to develop a current feedback value. The current estimator (68) is coupled to a rotor position detector (72) and an input power detector (78) and receives a signal representing motor torque angle to develop a signal representing the estimated current drawn by the motor (12).
