摘要：

The described speed control system uses the variable frequency principle. High performance and efficiency are obtained by a sinusoidal modulation of the width of the pulses supplied to the motor. A purpose-designed LSI circuit has been developed for signal generation. The analogue control system provides for the correct operation and protection of all functions. A fast dynamic response is obtained even under braking conditions.
