In an electric motor having a rotor which is arranged in a rotationally fixed manner on a shaft (4), a fixed bearing (7) is prestressed axially against a stop (9) by a spring element (11) in order to bear the shaft (4). The spring element (11) has an annular shape and has a larger external diameter than the fixed bearing (7). A rim (13), which is produced by peening, of the bearing plate (5) engages behind the external circumference of the element (11).

An electric toothbrush includes a handle, a brush head with bristles fixed thereto, a reciprocating bar, an actuator that moves the reciprocating bar back and forth, an actuator receiving recess, an engaging device that engages the brush head with the reciprocating bar so that the brush head moves relative to the reciprocating bar in either penetration mode or polishing mode and a selection device that places the engaging device either in the penetration mode or the polishing mode. The reciproca...

A positive side main contactor serving as a contact switching device on the positive side, which is connected between a positive electrode terminal of a battery pack and a high potential input terminal of an inverter, and a negative side main contactor serving as a contact switching device on the negative side, which is connected between a negative electrode terminal of the battery pack and a low potential input terminal of the inverter, are arranged so that moving contacts of these are moved fo...

An electric motor comprising a rotor and a stator is disclosed. The rotor is supported on a substantially spherical bearing and is of a substantially spherical design facing the stator, which has a high degree of efficiency. The stator may have a magnetic return-path body which is made of a compressed powder material. The return-path body may be of a substantially spherical design, at least in segments facing the rotor.

An electric connector includes a plug terminal 15 and a connector housing 2. The plug terminal 15 has a contact portion 15.sub.1 in one end and an electric wire connecting terminal 15.sub.3 in the other end, and the connector housing 2 accommodating the plug terminal. In the plug terminal 15, the contact portion and the electric wire connecting portion are connected through an elastic spring portion 15b, the connector housing 2 accommodates both the plug terminal 15 and a gate member 10 which ho...

An electric connector includes a connector body 2 having contacts, and a connector housing 10. The connector housing 10 has a cavity 12, for housing the connector body 2, and an operation lever 16. The connector body 2 is inserted into the cavity 12, and the electric connector is engaged with another connector by rotating the operation lever 16. The connector housing 10 has a sensing member 13 on one of its sidewalls. The sensing member 13 resiliently changes its shape according to insertion con...

An electric watch is characterized by including a transmitting circuit 6 for generating a plurality of transmitted signals, transmitting electrodes 1 and 2 for outputting the output signals generated by the transmitting circuit 6, a signal modulating member 3 composed of a rotor arranged adjacently to the transmitting electrodes 1 and 2 in a non-contact manner for modulating the transmitted signals, a receiving electrode 4 arranged adjacently to the signal modulating member 3 in a non-contact ma...

A rotating electric machine according to the present invention includes: a rotation axis extending along a first direction; a first rotor for coupling with the rotation axis to rotate together with the rotation axis; a first stator disposed so as to oppose the first rotor; and a moving mechanism for moving the first rotor so that relative positions of the first rotor and the first stator are changed.

A universal motor which operates an electric tool is controlled by a phase-gating controller for determining variable rotational speeds. The phase-gating controller can be switched over to wave-packet-controlled phase-gating control mode in order to be able to switch over between a continuous speed-torque characteristic and pulsating operation.

An electric drive has a cabinet with fixation points from which each includes a resilient web construction made of a first synthetic material which is partially surrounded by a second synthetic material in order to absorb vibrations. Thus in choosing adequate elasticity of the synthetic materials the electric drive can safely be secured by means of its fixation points thereby avoiding undesired resonance.
