    Abstract: The invention relates to a method for determining the delivery rate of a pump. In this context, a value of the delivery level and a value of the power of the pump are determined. A probability density function is calculated for the delivery level and the power. A first probability density function of the delivery rate is calculated on the basis of a delivery level-delivery rate relationship and the probability density function of the delivery level. A second probability density function of the delivery rate is determined on the basis of a power-delivery rate relationship and the probability density function of the power. A combined probability density function of the delivery rate is determined on the basis of the first and second probability density functions. The delivery rate is determined on the basis of the combined probability density function.

    Abstract: A displacement pump arrangement, method for operating the displacement pump arrangement and a control device for controlling the displacement pump arrangement provide rotational-speed-variable control of an expeller pump unit for feeding a fluid. The arrangement includes an expeller pump and a drive, the drive being composed of an electric drive motor and a frequency converter, and a control device. The control device controls a state value such as a final pressure of the expeller pump a setpoint value. The control device detects state values of a control variable are supplied by the drive, in particular relating to the position, rotational speed and torque of the drive motor, and adjusts the displacement pump output to reach the setpoint value without using sensors.

    Abstract: A rotor for a reluctance machine is provided. The rotor includes a soft magnetic element which is cylindrical in shape. The soft magnetic element has recesses forming flux barriers. At least part of the recesses are filled with an electrically conducting and magnetically non-conducting filler material such that a starting cage is formed in a peripheral region of the rotor. The ratio of the surface of the filled region of the flux barriers to the surface of the region of the unfilled flux barriers is at least 0.2 for at least one rotor cycle.

    Abstract: A rotor for a reluctance machine is provided. The rotor includes a cylindrical soft-magnetic element having cutouts for forming magnetic flux barriers. Some or all of the flux barriers are divided by one or more webs, with the profile of the individual webs forming a closed line which divides the rotor in the radial direction into an inner and an outer region. The cut-outs may be partially or fully filled with a a paramagnetic or diamagnetic filler material.
