Method for managing transitions in a three-phase BLDC motor and corresponding device
Abstract:
A method is provided for managing at least one transition in a three-phase BLDC motor describing a cycle including six successive states, wherein the motor obtains first, second and third synchronization signals. The synchronization signals are respectively associated with first, second and third coils of the motor. The method includes the following steps, for each current transition associated with the switching of the motor from a current state to a next state: selecting a current synchronization signal on which the current transition is to appear; detecting the occurrence of the current transition on the current synchronization signal; and sending, to the motor, at least one current control signal so as to switch the motor from the current state to the next state.
