Abstract

PURPOSE: To promote an elinination of shortage of torque, byuch means that with a ratio of terminal voltage and primary frequency held at a constant value, further with those of values raised to a level so as to obtain a required torque in a range of low frequency, simultaneously a compensation be made in accordance with a change of load.
