ABSTRACT:
A method for determining a change in direction of rotation of a motor includes the steps of establishing steady state operating parameters of the motor, triggering a command interrupting the rotation of the motor, estimating the speed of the motor after triggering the command and determining the instant from which the speed of the motor is below zero. This instant corresponds to the change in direction of rotation of the motor. The instant from which the motor changes direction of rotation can be determined accurately.
