An electrical switch has a common contact body and a first selective contact body and a second selective contact body. A contactor is connected mechanically and in an electrically conducting manner to the common contact body. The contactor comprises an elastic, electrically conducting material. It is formed originating from the basic form of a leaf spring into a multifunctional part having a clamping area, a deformation area and a stiffened actuating area. The pre-tension of the contactor causes...

The invention relates to an electric motor comprising a stator and a rotor. The stator and/or rotor comprise winding carriers (2, 2.1) with a respective winding (5) and at least two respective terminal connections. The two adjacent winding carriers (2, 2.1) are joined to each other or to the stator and/or rotor by means of a common fixing element (15).

A dynamo-electric motor applies motive power to a drive wheel. A battery supplies electric power to the dynamo-electric motor with a driver for controlling the driving of the dynamo-electric motor. A battery control unit performs a control of charging and discharging of the battery. A speed meter displays predetermined information relating to a vehicle. In the electric vehicle including the elements described above, the battery control unit obtains the vehicle speed, the total travel distance, a...

This electric fence comprises at least one electrically conducting metal wire (1) with good mechanical properties, associated with a support, and further incorporates at least one other electrically conducting wire (4) with good electrical conductivity, sheathed with an insulating material (5) over its entire length except for zones distributed at more or less regular intervals where the said conducting wire (4) is in direct or indirect contact with the said conducting metal wire or wires (1) wi...

An electrically driven gripper has a housing, a gearmotor attached to the housing, a cam engaged to the gearmotor, a pair of opposing jaws slidingly mounted to the housing, a cam follower secured to one of the jaws and in sliding contact with the cam; and a spring configured to impart a force to the jaws such that the jaws are pulled toward each other. The gearmotor drives the cam to force the jaws to a maximum open position. Continued rotation of the cam allows the spring to pull the jaws close...

An electric generator is disclosed, which comprises: at least a magnet, each having more than two poles; and at least a claw-pole set, each being composed of an inner claw-pole and an outer claw-pole; wherein, the inner claw-pole and the outer claw-pole are interlaced arranged and used for guiding magnetic flux; the inner claw-pole is connected to an iron core whose outer diameter is smaller than the magnet and thus the loop of the inner claw-pole and the outer claw-pole is conducted; the core i...
