摘要： This invention relates to electric drives. An electric drive comprising at least two gate-controlled electric motors, each of said motors comprising a synchronous machine having a rotor position sensor mounted on the shaft thereof, gate switching means provided with gate switch on and off control circuits, the output of said switching means being connected to armature winding sections of the synchronous machine, according to the invention, characterized in that said gate switch on control circuits of each of said gate switching means are connected to one output of the rotor position sensor of each subsequent synchronous machine thereby forming a ring circuit. This invention may find its use in the fields where stringent requirements are imposed upon synchronization of the electric drives.
