摘要： A method and a device for protecting an electric motor in a pod unit for propulsion of marine vessels against shaft bending shocks when the blades of the pod propeller hit ice blocks or other hard objects, said motor having a drive shaft, a rotor and a stator, said shocks tending to momentarily bend the drive shaft (3) to such an extent that the rotor (41) will come into contact with the stator. The rotor is prevented from coming in detrimental contact with the stator by providing at least two members, which together form a radial plain bearing having mating arcuate bearing surfaces, which during normal operation of the motor are spaced from one another by a gap and come in contact with one another only at extreme loads with short durations.

摘要： A restricting member is provided that is in contact with respective bent lead portions of a long-sized lead and a short-sized lead and imparts a tension to linear lead portions thereof in a mold for insert molding. The restricting member reliably prevents the leads from displacement and deformation resulting from the pressure of the resin at the time of insert molding, and allows the long-sized lead and the short-sized lead to be disposed at proper positions in a molded body.

摘要： An electrical machine, especially a generator for vehicles, having a rotor rotatably supported in a stator housing is proposed, the rotor having an exciter winding (24), disposed in a manner fixed against relative rotation coaxially to a rotor shaft, the winding ends (26, 28) of the exciter winding being extended to wiper rings disposed on the rotor shaft. For the sake of simple centrifugal force-proof fixation of the exciter winding, it is provided that the exciter winding (24) is disposed on a winding carrier (11), which has means (32, 33) for firmly clamping the winding ends (26, 28) (FIG. 2).

摘要： In the case of thermal power installations in which a gas turbine and a steam turbine jointly drive a turbo generator, the slip rings (8, 9) are arranged on a separate slip ring shaft (14) which is connected to the actual shaft or machine shaft (10) of the electric machine by means of a first detachable coupling (11). The slip ring shaft is provided on its end averted from the electric machine with a coupling flange (15) which is not connected to the slip ring shaft (14) by welding until after the slip rings (8, 9) have been pushed on. The use of an expensive shrink-on coupling between the turbo generator and steam turbine is avoided in this way without increasing the overall length of the turbo generator.

摘要： An eddy current drive has an electromagnet and an armature. Either one of the electromagnet or the armature is coupled to a motor shaft so as to rotate therewith, while the other is coupled to a load portion. The motor can rotate at a continuous speed, while the speed of the load portion can vary by varying the energization of the electromagnet, so as to vary the coupling between the electromagnet and the armature. The electromagnet is energized by way of bearings. The bearings provide a rotary coupling. In another embodiment, an electrical generator is provided. The rotation of the motor shaft generates electrical current that is used to energize the electromagnet. The amount of the electrical current that is provided to the electromagnet can be varied to vary the output speed of the load portion.

摘要： A brushless shaft mounted eddy current drive has a coil mounted to bearings by way of a coil mount. The bearings are located on a hub. The coil mount is anchored to a fixed object. The pole pieces are coupled together by a nonmagnetic material to form a cavity that receives the coil. In another embodiment, a brushless drive has a coil rotatably mounted in a cavity within the pole pieces. A rotary inductive coil is mounted to the pole pieces about a stationary inductive coil. Alternating current is provided to the stationary coil to induce current into the rotary coil. In still another embodiment, an alternator is used to induce current into the rotating coil. In still a further embodiment, a brushless drive incorporates a liquid conductive rotatable coupler in the hub. In still another embodiment, the brushless drive energizes the coil in the electromagnet by way of bearings. The bearings are mounted onto a shaft that is coupled to the electromagnet. The shaft is located at one end of the drive, while a motor shaft is received by the opposite end of the drive.
