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.
