Abstract
The invention relates to a method for generating control signals for managing the operation of a synchronous motor with one or more permanent magnets (1) comprising a stator (2), the stator comprising a number P of phases (3, 4, 5), a rotor, the rotor comprising said permanent magnet or magnets, a switching module (6) provided with a plurality of switches (K1-K6), a number N of Hall-effect sensors sensitive to a rotating electromagnetic field induced by said permanent magnet or magnets, N being no lower than 2 and strictly lower than P, the method comprising a step of acquiring status information transmitted by the sensors (9, 10) and a step of estimating at least one piece of complementary information on the basis of status information transmitted by the sensors (9, 10), the complementary information characterizing the status variation of at least one virtual sensor. The invention also relates to a control device (10) comprising a module for estimating a piece of complementary information (11) and a module for generating control signals (12) configured to implement the method. The invention further relates to an actuator (9) comprising a synchronous motor with permanent magnets (1…
