(EN) MULTI-VOLTAGE MOTOR CONTROLLER
(57) Abstract
(EN)

The present disclosure relates to a three-phase induction motor adapted to be operated at three or more different voltages with consistent speed and torque characteristics. The three-phase motor comprises a rotor, a stator having a plurality of slots, each slot comprising two or more concentric windings with a variable number of windings turns, and a multi-voltage motor pump (MVM) controller. The MVM controller comprises a voltage detection module configured to detect an input voltage, a current detection module configured to sense the current consumption rate of the three-phase motor, a plurality of solid- state switches pre-configured to connect the two or more concentric windings of the stator in a predetermined connection pattern, and a drive circuit adapted to automatically select at least one Solid- state Switch to operate the induction motor at multiple voltages.
