  • Patent number: 10164485
    Abstract: A stator-rotor device for an electrical machine, in particular an electric motor, includes a stator and a rotor, wherein the stator-rotor device pole cores provided with windings comprise pole shoes and magnets associated therewith. The pole shoes are connected via a first surface to a respective pole core and have a second surface that is facing towards the magnets. The pole shoes cooperate magnetically with the magnets and are separated from the latter by an air gap. The pole shoes and the magnets engage with one another in an engagement direction in such a way that in each case a section of the other component—magnet or pole shoes—is arranged lying opposite the respectively engaging component—pole shoe or magnet—transverse to the engagement direction on two sides facing away from one another. The second surface is larger than the first surface.

  • Publication number: 20150064021
    Abstract: A pump unit including a pump and an inverter drive, the inverter drive including a motor for driving the pump, a control unit for controlling the motor and a storage unit operatively connected to the control unit. The storage unit has stored therein a control program which determines the range of functions and/or the mode of functioning of the pump unit. The motor is controllable by the control unit depending on the control program. The pump unit includes a communication unit which is configured for establishing a contactless communication link with an external configuration device and that configuration data is transmittable, via the communication link, from the configuration device to the pump unit. The control program stored in the storage unit is modifiable for changing the range of functions and/or the mode of functioning of the pump unit depending on the configuration data transmitted.
