<p>The invention relates to a control system with auto-switching for a brushless motor (10) powered according to a pre-determined electric cycle to make the rotor advance. The inventive control system comprises a device (100) to indicate the mechanical position of the rotor associated with a detection device (50) forming a device (150) for the incremental coding of the mechanical position of the rotor. The system also comprises a motor control assembly comprising a means for processing (20) the rotor mechanical position coding signals connected to a means for regulating (30) the power supply of the numerous stator windings. The rotor mechanical position indicator device comprises at least one series (101) of rotor mechanical position indications corresponding to the passage of an electric stator cycle such that the incremental coding device (150) delivers a synchronisation signal for all the electric cycles to the processing means.</p> |
