  • Patent number: 6998813
    Abstract: The invention provides a device to generate an rpm-dependent signal, or a tachogenerator, having a plurality of magnet elements with alternating polarity which are arranged and distributed around the circumference of the rotor shaft. The magnet elements preferably take the form of a magnetic ring which has alternatively polarized sections and is held on a support attached to the rotor shaft. The tachogenerator of the present invention has at least one coil parallel to the axis which is arranged on a second supporting device at an axial distance to the magnet elements. The magnets and coils are arranged spatially relative to each other and can be rotated in relation to each other with the rotation of the rotor shaft in order to induce an rpm-dependent signal in the coils. In accordance with the invention, a signal displacement device is provided which superimposes a DC voltage on the signals induced in the coils in order to generate a voltage-displaced signal.

  • Patent number: 6873072
    Abstract: The invention relates to a relay supporting unit for an electric motor to arrange a number of relays at the end of the electric motor, at which winding connections and signal lines of the electric motor are provided. The relays are used to connect and interrupt the power supply to the motor windings. The relay supporting unit according to the invention features a supporting component which is designed in such a way that it extends over the end of the electric motor and has at least one, preferably several, chambers to accommodate and position the relays. A connecting frame is integrated into the supporting component to electrically connect the winding connections and the relays. Furthermore, a sensor PCB is also preferably integrated to which the signal lines of the electric motor can be connected.
