Abstract

PURPOSE:To shorten the starting time and to suppress the starting current low by providing a frequency and voltage pattern used for starting only, and starting a motor under this condition. CONSTITUTION:A monostable multivibrator 53 receives a control input 8 and a starting data 51, and operates in response to the control input. A data selector 54 selects and outputs either the control output or the starting data based on the control signal from said monostable multivibrator. The output from the data selector 54 is sent to an ROM 7 wherein the frequency and voltage pattern is stored, and to a rate multiplier 4, which sends and AC frequency from an original oscillating circuit 3 to an electric angle counter 6. The output of the electric angle counter 6 is given to the ROM 7. A base driving signal is outputted from said ROM, and a main circuit is controlled. In this constitution, starting is always made from a point 71 in the Figure. The output frequency of the inverter is gradually increased to a point 21. Then the data selector selects the control input 8, and the speed of the motor increases toward a point 22.
