For self-switching control of a brushless motor ( 10 ) powered by means of a predetermined electrical cycle in order to cause the rotor to advance, the control system comprises an indicator device ( 100 ) for indicating the mechanical position of the rotor, the device being associated with a detector device ( 50 ) forming an incremental coder device ( 150 ) for encoding the mechanical position of the rotor. The system also comprises a motor control assembly made up of processor means ( 20 ) for processing the signals coding the mechanical position of the rotor connected to regulator means ( 30 ) for powering the plurality of stator windings. The device for indicating the mechanical position of the rotor comprises at least one series ( 101 ) of indications of the mechanical position of the rotor corresponding to passing through one electrical cycle of the stator, whereby the incremental coder device ( 150 ) delivers the processor means with one synchronization signal for each electrical cycle. |
