METHOD FOR CONTROLLING OF A MULTIPHASE ELECTRIC MOTOR OPERATING IN STAR-CONNECTED MODE VERFAHREN ZUM ANSTEUERN EINES MEHRPHASIGEN IN STERNSCHALTUNG BETRIEBENEN ELEKTROMOTORS

摘要

The method is used to start up a multiphase electric motor operating in star-connected mode.  The method provides for conductive bridging of at least one coil portion of one phase of the motor and electrical separation of the bridged coil portion, in order in this manner to supply a higher voltage to the electrically active, remaining coils and thereby to increase the current flux and thus the torque.
