FIELD: electrical engineering; induction-motor thyristor drives.
SUBSTANCE: proposed general-purpose industrial drive characterized in stepless starting and speed governing by means of thyristors dispensing with shaft-mounted speed sensor that can be used for driving fans, compressors, pumps, grinding machines, conveyers, horizontal-travel mechanisms of material-handling machines, and the like has induction motor, thyristor voltage converter, control unit, speed governing unit, rotation speed setting unit, stator internal voltage meter, motor current and voltage sensor, and functional unit.
EFFECT: enhanced precision of speed control.
