    摘要： An electronic module is provided including power switches mounted on a circuit board and configured as an inverter circuit for an electric motor. A sliding member is coupled to an actuator. A power contact switch is provided including a first conductive body, a second conductive body, and a contact switch. The first and second conductive bodies are mounted on a first surface of the circuit board and include pins received through through-holes of the circuit board to make electrical contact with two conductive tracks on a second surface of the circuit board. The contact switch pivotably is secured to the first conductive body and pivotably moveable by the sliding member to make contact with the second conductive body with movement of the actuator. A flyback diode is electrically connected between the first and second conductive track on the second surface of the circuit board parallel to the power contact switch.

    摘要： A method of using a superconductor to generate energy. The superconductor is alternated between a temperature above and below a critical temperature defined by a transition between the superconducting and non-superconducting state. The superconductor interacts with a magnetic field as the superconductor changes states. Energy is harnessed by coupling with the magnetic field as its strength fluctuates. The method would be particularly suitable for harnessing solar energy in space.

    摘要： In an ordinary DC motor in a windshield wiper, operating speed tends to increase as the motor brushes become seated. The invention counteracts this tendency by providing a brush geometry which causes the effective angular position of a brush to change during seating. The change is in a direction which tends to reduce speed.

    摘要： In the case of a universal electric motor for any kind of drive, with a stator package, a rotatably mounted rotor with commutator, as well as end shields on both sides that also constitute the bearings for the rotor and a switching ring that can be rotated through predetermined angular amounts and carries the (carbon) brushes, it is proposed to insert into the end shield A a closely fitting anchor block that serves for locking together the two end shields with the intervening stator package; further, the switching ring can be mounted on an external annular end face of the end shield B that also carries the switching strips or switching rails needed for switching between clockwise and counter clockwise rotation, complete with contact areas situated in the plane of the annular end face and suitable for axial contacting, the said contact areas making contact with other axial contact areas on the switching ring to establish connections with the carbon brushes.

    摘要： The invention concerns a device for mounting a pair of carbon brushes in an electric hand tool. To allow for the reversibility of the motor the device is mounted rotatably relative to the shaft of the motor. Further, the device is also used on the switch for reversing the polarity of the field windings by having a handgrip extending outside of the motor housing and having contacts for contacting relative fixed contacting strip members. By further using a bayonet-shaped structure, construction is simplified and the number of total parts is reduced.
