In this paper, the transient state equations and vector control algorithms of an induction type servomotor are described mathematically by using the two-axis theory(d-q coordinates). According to the result of these algorithms, we scheme the speed control system for the motor in which vector control is adopted to give it high performance. Motor drive through a PWM inverter with power MOS-FET is controlled so that the actual input current to the motor may track the current reference obtained from a microcomputer(8086 cpu). Driving experiments are performed in the range of 0 to 3000 rpm, and it xt is verified that high speed response is possible.<br/>
