  • Patent number: 12512730
    Abstract: An electric drive may include an electric motor phase terminal for phase current measurement. The electric drive may include an inverter, an electric machine having a plurality of phase current branches, the electric machine and the inverter being arranged together in a housing, and the one magnetic field sensor without a magnetic core for measuring a current of at least one of said plurality of phase current branches. At least one phase current branch of the plurality of phase current branches may include a slot bar which is arranged at least partially in a slot of the electric machine and which forms a phase terminal outside the slot, and the phase terminal may have a curvature in the region of which the at least one magnetic field sensor without a magnetic core is arranged.

  • Publication number: 20240195316
    Abstract: An electric drive may include at least one electric machine and at least one inverter having at least one power system adapted to supply power to the at least one electric machine. The power system may include a busbar system coupled in an electrically conducting manner to a DC power source, at least one capacitor coupled in an electrically conducting manner to the busbar system, at least one semiconductor switch coupled in an electrically conducting manner to the busbar system, and at least one phase terminal coupled in an electrically conducting manner to the at least one semiconductor switch. The at least one part of the at least one power system is coupled in a thermally conducting manner to at least one part of the electrical machine in order to dissipate heat from the at least one part of the at least one power system.
