Definitions

  • the invention relates to an electric motor with an electronics unit and a housing.
  • Switching devices consist in the simplest case of relays that control, for example, different power levels of an electric motor.
  • the relays are located either in a relay box, such as a relay box of a vehicle, or in a separate electrical assembly, which in turn is housed in a separate housing.
  • the switching device or electronics of a vehicle includes individual components such as plug contacts to the electrical system, plug contacts to the control unit, plug contacts to the engine and the vehicle ground. Since the electric motor usually already has a compact design, switching device and a necessary protective device can not be integrated into the electric motor.
  • the object of the invention is to develop an electronic unit such that, in addition to a switching device, it also comprises a protective device, which are arranged in a housing.
  • the electronic unit has at least one switching device and at least one protective device.
  • the switching device is used for controlling and / or regulating the electric motor.
  • the protective device detects binding and / or blocking of the electric motor.
  • the switching and protection devices are thus arranged in an electronics unit and a housing.
  • the electronics unit may also contain other electronic components.
  • the electronic unit has a printed circuit board on which the switching electronics and the protective circuit are arranged.
  • further electronic components can be arranged on the printed circuit board.
  • the printed circuit board preferably has connecting elements.
  • the switching device and the protection circuit are connected to each other by means of one of these connecting elements.
  • the housing is sealed against environmental influences, such as dirt or water, and has a pressure compensation element.
  • the electric motor and the electronics unit are firmly connected.
  • a connection may, for example, be a cable element, such as a motor cable.
  • the electric motor is preferably designed as a DC motor, in particular electronically commutated DC motor.
  • the electric motor is provided as a radiator fan motor for installation in a motor vehicle.
  • the integrated switching and protective device protects the electric motor against overload as well as thermal damage or even destruction. Furthermore, the number of interfaces is reduced, since now there is only one interface between the electric motor and the electronics unit. In addition, the assembly effort is reduced because no longer electronics unit and separate protection device are to be mounted, but only one electronic unit.
  • Fig. 1 is a schematic representation of an electronic unit according to the state of
  • Fig. 2 is a schematic representation of an electronic unit with integrated
  • Fig. 3 shows an electric motor according to the invention with electronics unit.
  • Fig. 1 shows a schematic representation of an electronic unit 3 according to the prior art.
  • the electric motor 1 is connected by means of plug 4 with the electronic unit 3, which has the switching device 2.
  • the control of the switching device or electronics 2 via a control signal, which is supplied via the input 5 of the switching device 2.
  • the switching electronics 2 is supplied with the necessary voltage.
  • the ground terminal 7 is shown, with which the electric motor 1 is connected via the plug 4.
  • the electronic unit 3 has no integrated protection circuit.
  • the switching device 2 shows a schematic representation of an electronic unit 3 with integrated switching device 2 and protective device 12.
  • the switching device 2 is used for switching the electric motor 1.
  • the protective device 12 detects binding and / or blocking of the electric motor 1.
  • the switching device 2 and the protective circuit 12 are thus arranged in an electronics unit 3.
  • the electric motor 1 is connected via the connecting element 9 with the electronic unit 3.
  • the control of the switching device 2 via the control signal 5. Via the terminal 6, the switching device 2 is supplied with the necessary voltage. Furthermore, the ground terminal 7 is shown.
  • FIG. 3 shows an electric motor 1 according to the invention with the electronic unit 3.
  • the electronic unit is arranged in the housing 8.
  • the switching and protective devices 2, 12, not shown separately, are thus arranged in an electronic unit 3 and a housing 8.
  • the housing 8 is sealed against environmental influences, such as dirt or water, and has a pressure compensation element, not shown.
  • the electronic components power connector 10 and signal connector 11 are shown.
  • the electric motor 1 and the electronic unit 3 are fixedly connected to each other by means of a connecting element 9, in particular a cable element.
