Title: Electronic encoder for automatic torque control of SRM
Inventor: AHN JIN WOO
IPC: H02P25/08
Filed: 2001-05-02
Abstract: PURPOSE: An electronic encoder is provided to stabilize SRM driving system and reduce cost by eliminating the need of using a speed detector for controlling speed of motor. CONSTITUTION: Position and speed of a motor are detected, in pulse signals, by a disk type encoder, and the reference speed is simultaneously detected in pulse signals. Speed-torque characteristic of SRM is controlled by the size of current of excited electromotive force, and the size of the current is controlled by an advance angle. When the load torque increases/decreases in a synchronous machine, compensation error also increases/decreases, and the torque output corresponds to the increase/decrease. When the load torque increase/decreases in an SRM, dwell angle of current increases/decreases without using an additional arithmetic device, and an effective torque output is obtained in proportion to the square of the instantaneous current, to thereby improve torque characteristic of motor.

Inventor: NAKAMURA MASASHI
IPC: F02D41/02
Filed: 2001-06-29
Abstract: PURPOSE: To make it possible to consistently respond to load fluctuation with reserve capacity without being influenced by change in the output of an engine or a generator due to aged deterioration or the like. CONSTITUTION: The output current of the generator 1 is rectified by a converter 3 comprising a thyristor bridge and an inverter 4 converts direct currents outputted from the converter 3 into alternating currents of commercial frequency and connects the currents to a load 5. A fuel quantity control portion 10 controls the number of revolutions of the engine 2 so that the conduction angle of the thyristors comprising the converter 3 is held equal to a target conduction angle. By setting the target conduction angle to a value within an intended range less than the maximum conduction angle, the generator is capable of consistently and swiftly responding to any load fluctuation with reserve capacity. If the throttle opening is too large, as a result, the target number of engine revolutions can be increased with the reduced target conduction angle so that the engine 2 is not overloaded and the number of revolutions thereof is not unnecessarily increased.
