The first and second metal layers consist of a plurality of metal stripes in parallel with each other in alignment with each other, respectively. Terminal elements of the metal stripes comprises on one sides or on both sides thereof wire positioning walls to facilitate soldering of wires to the terminal elements. By folderin...

An electric connector (100) includes an insulative housing (2) having front and rear walls (21, 22), a terminal passageway (23) defined between said front and rear walls and having top and bottom walls (25, 24), and a conductive terminal (3) assembled to the insulative housing to be retained in the terminal passageway and having a base wall (31) and a pair of spring arms (32) extending from the base wall and adapted for mating with said pin terminal. The pair of spring arms face to each other an...

An electric pump comprises a case in which a core being enwound by a coil is embedded, a permanent magnet formed in a cylindrical shape, having a central axis being identical to that of the core, and positioned so as to face an inner peripheral side of the core, an outer rotor fixed to an inner peripheral side of the permanent magnet, a rotor unit including the permanent magnet and the outer rotor, an inner rotor having a central axis, which is eccentric from a central axis of the core, so as to...

An electric motor has a hollow-cylindrical motor housing containing end plates that are mounted in the motor housing via respective centering flanges. A discrete electrical component is connected in parallel to electrical connections of the electric motor that are formed by contact elements disposed on the first end plate. The component is linked with at least one of the contact elements via a lead. The lead is inserted in a first, substantially V-shaped groove that tapers in the direction of in...

The electric motor is equipped with an electronic control, for example in the form of a frequency converter (2) and comprises at least one Seebeck element (6) whose one side is connected to the motor (1) in a heat-conducting manner and whose other side is in heat-conducting connection with a cooling medium. The electrical output power of the Seebeck element (6) is led to the electronic control (2) of the motor (1).

An electric cooking assembly includes a main body portion that defines a cooking area. First and second cooking surfaces are contained within the cooking area. A first electric heating element arranged to provide heat to at least a portion of the first cooking surface, and a second electric heating element is arranged to heat at least a portion of the second cooking surface. The main body portion may include first and second hood members. The first hood member defines the cooking area and the se...

An electrically powered bicycle includes a hub motor, which is mounted to the bicycle frame by its axle. A drive sprocket mounted to the outer case of motor is engaged by a chain to the sprocket on a multi-speed hub on the rear wheel, so that when the motor turns, it drives the wheel. A freewheel, also mounted to the outer case of motor, is engaged by a chain to the large sprocket on the pedal crank, such that when the motor is operating, it does not turn the pedal sprocket. When the pedals and ...

An electric machine includes a stator having slots of substantially rectangular cross section. The slots are subdivided into pairs of slots, with each pair of slots configured with parallel flanks, wherein teeth are formed between the slots and have alternating rectangular and triangular cross sections. Positioned on the teeth of rectangular cross section are tooth coils.

An electric stapler comprises an enclosure, a motor, a power transmission device, a working arm pivotally attached to the enclosure, a magazine receiving a plurality of staples and a clinching assembly. A guide device is mounted upon the working arm and rotating therewith. The guide device defines a guideway therein. The magazine is slidably engaged with the working arm. The clinching assembly combines a blade support and a blade, both received in the guideway of the guide device and movable the...
