Method for minimising the phase errors during the driving of an electric motor, and a circuit using the method thereof
Abstract:
The present invention relates to a method and a circuit using the method thereof for minimising the phase errors during the driving of an electric motor, and a circuit using the method thereof, having a stator winding, a permanent magnet rotor assembly, and devices able to sense a rotor position, which comprises the following steps: a) generating of a rotor position signal (10, 14, 39), by means of said devices able to sense said rotor position; b) detecting at least two information from at least two edges (11, 12; 15, 16) of said rotor position signal (10, 14, 39) inside a measure period; c) generating a driving signal (9, 13, 38), in finction of said at least two information (11, 12; 15, 16) inside the measure period, so as to follow the rotor velocity.
