Patent ID: 7741797

Claim:
Method for managing at least one transition in a three-phase BLDC motor describing a cycle including six successive states, wherein said motor obtains first, second and third synchronisation signals, which are respectively associated with first, second and third coils of said motor, wherein, for each current transition associated with the switching of the motor from a current state to a next state, the method includes the following steps: selecting a current synchronisation signal on which said current transition is to appear; monitoring the current synchronisation signal but not other synchronisation signals; detecting the occurrence of said current transition on said current synchronisation signal; masking the current synchronisation signal, after the occurrence of said current transition, during a given time period; sending, to said motor, at least one current control signal so as to switch the motor from the current state to the next state; and determining, for each current transition, a predetermined time range in which said step of detecting the occurrence of said current transition is implemented.
