Abstract

PURPOSE:To make the control possible in accordance with the electric motor's instantaneous state by using a microcomputer for the electric motor's control and inputting an external signal indicating the electric motor's instantaneous state after being synchronized at each stage. CONSTITUTION:The electric motor 100 is driven through the intermediary of a rectification circuit 175 and an inverter 160. In addition, each signal of a phase detector 150, DC voltage, current, tempetature and command is input to I/O circuit 120 controlled by microcomputers 114-118. Reference registers containing an input information, instantaneous register, comparison circuit and a stage counter are provided. Their stage signals and a synchronized irregularly input external signal are input to an incrementer/decrementer to control the inverter 160. Consequently, it is possible to enable complicated control with the use of simple circuit and provide accurate operation because of signal synchronization.
