Abstract
A method for controlling an electric motor, implemented in a variable speed drive, the variable speed drive being connected to the electric motor through a transformer, the method including; executing an identification sequence of the transformer for determining gain data corresponding to an inverse function of a transfer function of the transformer; generating a transfer module based on said determined gain data; determining a start-up sequence of the electric motor to be implemented by the variable speed drive by executing the transfer module on a reference current path.
