    The present invention relates to a control method for a synchronous electric motor with permanent-magnet rotor, particularly for fluid circulation pumps in conditioning systems and/or household appliances, wherein the application of predetermined voltage values to each of the windings (L1, L2) of the motor is provided, by means of a converter control circuit (10). The method provides a continuous measure of the amplitude of the bus (Vr) ripple and a comparison with a reference value, for example with respect to an average bus voltage level. According to the comparison result the motor is driven by means of a variation of the winding voltage having an sinusoidal wave form.
