A method for starting a motor ( 14 ) with a bidirectional rotation direction, to rotate a fluid circulation centrifugal pump ( 10 ) having a predetermined optimum hydraulic efficiency depending on the starting rotation direction thereof. The method provides an initial motor ( 14 ) starting in either rotation direction, with subsequent pump ( 10 ) rotation in the same direction and, subsequently, a periodical interruption and restoration of the motor ( 14 ) power feeding as many times (N, N') as to ensure the motor ( 14 ) starting, at least one or more times within a predetermined time interval (T<SUB>tot</SUB>, T<SUB>s</SUB>), in the rotation direction which corresponds to the predetermined pump ( 10 ) optimum hydraulic speed.
