Abstract
PURPOSE:To produce a winding command for selecting an optimal winding connection automatically, by setting an available speed range of winding connection and judging winding connection based on a motor speed. CONSTITUTION:A selection switch 15 is connected to a memory circuit 13. When a motor is stopped, speed decision units 7, 8 go to 'L' and the output from the memory circuit 13 go to 'L', and thereby an inverter 2 take a control constant for low speed winding and a winding switching device 3 is connected to low speed winding. When a switch 14 is closed to provide a motor speed command NREF from a speed command unit 1, the motor is operated with low speed winding so long as the speed command NREF<reference winding switching speed Ns. When NREF>Ns and actual speed NFB>reference speed Ns, speed decision units 7, 8 go to 'H' while the output from an AND gate 11 go to 'L' and the output from the memory circuit 13 goes to 'H'. Consequently, the inverter 2 takes a control constant for high speed winding and the winding switching device 3 is connected to high speed winding.
