Abstract:
1. A method for generating control signals (Sw 1 , Sw 2 , Sw 3 ) for a polyphase rotary electrical machine ( 2 ) comprising phase windings ( 4 ) each defining a phase of said electrical machine and rotor position sensors ( 1 ) for determining angular position of a rotor of said electrical machine such that a number of said sensors equals to the number of said phases, said control signals (Sw 1 , Sw 2 , Sw 3 ) controlling a power supply ( 10 ) to said windings ( 4 ), said method comprising the steps of: generating synchronization signals (Si forming said control signals (Sw said synchronization signals (Si generating rising and falling edges of said out-of-phase signals (So
