Abstract

PURPOSE:To achieve acceleration and deceleration within the shortest possible time by varying the slant angle with respect to the time of acceleration and deceleration of an AC motor corresponding to the output of a variable-voltage variable-frequency power supply depending on the rpm of the motor. CONSTITUTION:In the case a wind comparator W.C1 is turned on with the output voltage of a slant-signal generator 100 being zero, a switch K1 is turned on with the contacts of said switch K1 being closed, but switches K2 and K3 are turned off. At this time, when a reference voltage VR is inputted to a terminal 101, the output Vout rises at a slant angle with a time constant determined by the set value of a variable resistor VR1, a resistor R, and a capacitor C. When said output has risen up to the region set by a wind comparator W.C2, a switch K2 is turned on, and the switch K1 is turned off. Then, the output rises at a different slant angle. At the time of deceleration, the reverse operation is carried out.
