electrical engineering; fan-driving motors. SUBSTANCE: device for controlling induction motor 1 has slip control 10 and current control 12, uncontrolled rectifier 3, voltage control 4, set-input gate 9, first and second comparison gates 8 and 11, feedback unit 5, load detecting unit 7, and correction unit 6. The latter ensures transient and steady state stability of control system under varying parameters and loads of motor. EFFECT: enlarged functional capabilities, enhanced precision of slip control. 2 cl, 1 dwg
