Abstract
1502542 Electric motor W A BURTIS 16 Jan 1976 [20 Oct 1975] 01748/76 Heading H2A An electric motor has means 22, 30, 31 disposed between a wound rotor 25 and a rotatable wound field 26 so that the field and rotor rotate in opposite directions to one another, commutators 55, 65 on the field and rotor respectively, and rings (105), (115), Fig. 5 (not shown) carrying brushes contacting the field and rotor respectively, the brush rings (105), (115) being manually mutually adjustable to adjust the relative phase angle between the energized field and rotor windings. The field 26 has a shell 27 mounted on rotor shaft 15 via bearings 29, 37 received in plates 28, 38 secured to shell 27, a gear ring 30 on plate 28 meshing with planetary gears 22 which are located on fixed bearings 21 and engage a sun gear 31 on rotor shaft 15. End plate 13 supports the stationary rings (105), (115), carrying exciting brushes (101) to (104) and (111) to (114) respectively commutator 55 is attached to a spacer ring 51 compressed against an electrically insulating washer 49 by a cap 52 bolted 53 to shell 27. Rings (105), (115) have handles (106), (116) respectively to allow relative adjustment therebetween by movement around the motor axis. Additional brushes (107) to (110), Figs. 3 and 6 (not shown), mounted on ring (105) and lagging the field exciting brushes pick up the field collapse transients and return some of the field collapse power via a power amplifier (150) and rectifier (151) back to the field-exciting battery (300). Additional brushes (117) to (120) on the ring (115) engage the rotor commutator 65 for a similar purpose.
