PROBLEM TO BE SOLVED: To provide an AC motor controller capable of being switched with external signals, reduced in cost and size, and preventing the occurrence of accidents, etc., which result from switching delay by outputting operation identifying signals. SOLUTION: An AC motor controller is provided with an AC motor control arithmetic section and a power converting circuit 15. The arithmetic section consists of a synchronous motor control arithmetic section 11 for driving a synchronous motor 2s and an induction motor control arithmetic section 11i for driving an induction motor 2i and is provided with switches 14s and 14i for switching the arithmetic sections 11s and 11i. |
