  • Publication number: 20230356704
    Abstract: The disclosure relates to an electronically commutated machine, more particularly an electronically commutated motor having a rotor on a rotor shaft, which rotor shaft can be actuated to rotate. For sensing of an angle of rotation of the rotor shaft, a signaling means is provided, which comprises a retaining element and a magnetic element disposed on the retaining element. A retaining element made of ferromagnetic material is proposed, the magnetic element being placed onto the retaining element from the outside and being retained thereon by magnetic force. The proposal makes it possible to dispense with costly adhesive connections between the magnetic element and the retaining element. The disclosure further relates to an electronically slip-controllable braking system having an electrically commutated machine.

  • Patent number: 9512930
    Abstract: A pilot-controlled pressure control valve is disclosed. The pilot-controlled pressure control valve has a pilot control stage, a spool valve, and an overload spring. The pilot control stage includes a pilot control piston which has a pilot control spring. The pilot control spring acts in a closing direction of the pilot control stage. The pilot control spring is supported on the spool valve which can be positioned by a control pressure against the force of the overload spring. The control pressure is configured to set a preload of the pilot control spring. At the same time, in a loaded position, in which the pilot control valve has minimum preload, the spool valve rests against a stop. A preload of the overload spring and a position of the stop can be set independently of one another.
