Abstract: A rotor for a reluctance machine and a method of producing a rotor for a reluctance machine is provided. The rotor is formed as a soft magnetic element which is cylindrical in shape. The soft magnetic element has recesses for forming flux barriers, one or more flux barriers being at least partially filled with a filler material, and the filler material of said flux barriers extending up to the rotor periphery and forming part of the rotor periphery.

Abstract: A method for producing a rotor for a reluctance machine, in particular for a synchronous reluctance machine, and a rotor produced by the method, are provided. The laminated rotor core is produced by punching and stacking two or more adjacent laminations of the core. The adjacent laminations are held together by at least one connection point created during the punch stacking, the at least one connection point simultaneously forming a flux barrier of the rotor. The rotor comprises a laminated core, which is stacked from at least two lamination sheets, with the at least two adjacent lamination cuts being connected to each other by at least one connection point forming at least one flux barrier of the rotor.

Abstract: A method and apparatus for controlling the motor of a synchronous reluctance motor for a pump, in particular a centrifugal pump, are provided. The motor includes a variable-frequency drive which controls the synchronous reluctance motor in a terminal volts/hertz operation. The pump, in particular a centrifugal pump, includes at least one synchronous reluctance motor and a variable-frequency drive for a motor control, the variable-frequency drive being a terminal volts/hertz variable-frequency drive.
