Abstract: A method for adjusting a resolver of an electric machine is provided. A resolver rotor is an adjustable element of the resolver and mounted by friction on a support so that a relative angular position with respect to the support may be adjusted by exerting a torque between the resolver rotor and the support. The method includes steps of: measuring an offset angle of the resolver to be corrected; as long as the offset is not less than an predetermined tolerance, locking the resolver rotor with respect to a resolver stator; launching the correction by energizing a main stator of the electric machine so that the electric machine develops a correction torque causing rotation of the resolver rotor with respect to a shaft of the electric machine by the measured offset; and freeing the resolver rotor. Subsequently the method returns to the measuring step.
