INTELLIGENT ELECTRIC MOTOR WITH ELECTRICAL REDUNDANCY AND INTEGRATED FAULT DETECTION

Abstract

Intelligent motor (10), comprising: - an electromechanical transducer with permanent magnets (12); and - an electronic control unit (18); wherein the electromechanical transducer (12) comprises: - a rotor (121) with permanent magnets; and - a stator (122), comprising: - a first arrangement (123) comprising at least three phases electrically star-connected; - a second arrangement (124) comprising as many phases as the first arrangement, the phases of the second arrangement being electrically star-connected; and - an impedance between the star points of the stars of the first and second arrangements; wherein the electronic control unit comprises a control converter (184) comprising as many independent control arms (1840) as phases of the first arrangement and as many independent control arms as phases of the second arrangement;wherein the control inverter is configured to drive each phase of the first arrangement and each phase of the second arrangement by its own control arms; wherein the electronic control unit is configured to measure a voltage difference (VD12) between star points of the stars of the first and second arrangements with respect to a common voltage reference of the arrangements.
