Abstract:
A method for controlling the direction of rotation of a fluid machine having an oriented-blade impeller, comprising the following steps:
starting (100) a synchronous electric motor which operates said fluid machine until the synchronous state is reached;
driving (200) said synchronous electric motor at steady state by applying a phase cutting;
applying (300) a phase cutting corresponding to a reference power, wherein said reference power is comprised between a first power required to keep the propeller rotating in a right direction and a second power required to keep the propeller rotating in a wrong direction, which is opposed to the right direction.
