  • Patent number: 5493162
    Abstract: A pole core with pole lips serves for fixing a field winding in the pole housing of a direct current motor. The pole core has a central pole body mountable on an inner side of the pole housing. The pole lips are formed of one piece with the central pole body and are resiliently and springily connected to the central pole body, so that the field coil can be pressed against the pole housing in an elastic springy manner without additional spring elements, so that no damage occurs to the insulating coat of the coil.

  • Patent number: 5095864
    Abstract: In a starter device having two starters (11, 12) operating in parallel mode, for the purpose of ensuring that the switching on of the drive motors (17, 18) for the drive of the starting pinions occurs only after engagement of the latter, the relay windings (21, 22) of the starting relays (19, 20) which push the starting pinions forwards, are connected in parallel to one another and in such a way that they are excited simultaneously when the starter switch (16) is activated. After complete engagement of the starting pinions, in each starter (11, 12), switching contacts (27-30) are activated, of which two switching contacts (27, 30 or 28, 29) associated, in each case, with two different starters (11, 12), are series-connected and connected in series to, in each case, one drive motor (17 or 18). Thus, if necessary, the switching on of the drive motors (17, 18) is blocked as long as one of the two starting pinions is not engaged.
