Abstract (en)

[origin: FR2843248A1] The synchronised function control process has a star feed with coils and a rotor with a set of radially alternating magnetisation. Following detection (12) the motor (2,3) rotor positions are determined, and synchronisation logic (19) determines a single phase feed sequence and the phase feed is applied identically to aid the power electronics.
