  • Electric machine with a braced overhang
    Patent number: 5969460
    Abstract: In an electric machine (10), in particular a generator or motor, which is accommodated in a machine housing (11) and comprises a stator winding which passes through a stator core (13) and which merges on the end face into an overhang (31) which is mounted in a braced manner in order to absorb dynamic loads, flexible readjustment is achieved by providing, on the overhang mounting, means (20, 21, 29, 30) for retensioning the overhang (31) which are actuable from outside the machine housing (11) and which allow retensioning during operation.

  • Device for pressing slot sealing pieces for winding bars into slots of an iron body of an electric machine
    Patent number: 5778518
    Abstract: In a device (1) for pressing in slot sealing pieces (12, 14) for winding bars (20) inserted into the slots of a stator laminated core of an electric machine, a plunger (8) is arranged by means of a force-generating device (4) in a collet (2) with a cam (3). The plunger (8) and the cam (3) are situated opposite one another and move toward one another in the fashion of a screw clamp during operation of the force-generating device (4). In this arrangement, when slot sealing pieces are pressed in the cam (3) engages in an axial slit (11) of a first, upper prismatic body (12), and the plunger (8) acts on an end face (13) of a second, lower prismatic body (14). The device (1) for pressing in slot sealing pieces (12, 14) is arranged with lifting devices (22) on a support frame (23) which can be moved along the slot sealing pieces (12, 14) in the stator laminated core.

  • Device for monitoring corona discharge in a dynamoelectric machine with detection probe movable in longitudinal and circumferential direction
    Patent number: 5252927
    Abstract: In the device for detecting partial discharges in winding elements of an electrical machine, the winding element to be investigated is sampled over its length, with high voltage applied, by means of a drivable probe and the radio frequency signals initiated by the partial discharges are received by means of an antenna. The antenna signal is detected and evaluated in a test set (11) connected downstream. The probe is arranged on a support which can be conveyed, under remote control, in the machine longitudinal direction, by means of tension cables (4, 5) or an axle rod, or is provided with a dedicated drive.
