  • Patent number: 11381125
    Abstract: A rotor for an electric machine is provided. Permanent magnets are disposed on the rotor such that the permanent magnets cannot carry out any tangential movement. The rotor may have four shoulders that extend away from a shell surface of the rotor in a radial direction. Primary permanent magnets that are disposed so as to be mutually contiguous and contiguous to the respective shoulders and accordingly cannot be displaced are in each case located between the shoulders. Secondary permanent magnets are disposed on the shoulders such that an annulus of magnets that is free of gaps and voids and is not movable in the tangential direction is formed.

  • Patent number: 10774925
    Abstract: An electric motor equipped with a transmission unit in the form of a planetary gear transmission is provided. The planetary gear transmission has a sun gear, planetary gears, and a ring gear, which are coupled to one another via corresponding toothings. The sun gear is coupled directly to a shaft of the electric motor and is fastened thereto. The planetary gears or axles thereof are retained on a bearing plate of the electric motor. The ring gear is rotatably mounted on the housing of the electric motor or is fastened to the housing of the electric motor. A common feature is that parts of the transmission are retained on the housing of the electric motor and not on a separate housing or another component of the transmission unit.

  • Publication number: 20190154140
    Abstract: The invention relates to an electric motor equipped with a transmission unit, for example in the form of a planetary gear transmission. The planetary gear transmission has a sun gear, a plurality of planetary gears, and a ring gear, which are coupled to one another via corresponding toothings The sun gear is coupled directly to a shaft of the electric motor and is fastened thereto. The planetary gears or the axles thereof are retained on a bearing plate of the electric motor, such that the transmission unit does not have to provide any additional components for this purpose. In one embodiment of the planetary gear transmission, the ring gear is rotatably mounted on the housing of the electric motor. In an alternative embodiment, the ring gear is fastened to the housing of the electric motor.
