1,141,096. Engine turning gear. McCULLOCH CORP. Aug. 2, 1966 [Aug. 12, 1965] No. 34568/66. Heading F1K. [Also in Division H2] A diode 79 is so connected between an external circuit e.g. a battery 86 Fig. 3, and a compound wound motor-generator 11 of an I, C. E. D. C. starter motor-generator system as to block current flow from the battery to the motor-generator through a conduction path which includes the diode, and to permit current flow in the opposite direction when the motor-generator generates. In parallel with the diode is an electromagnetic starter switch 80 whose coil 102 is controlled by a manual switch 106. The shunt field winding wire size and number of turns are selected to decrease due to temperature rise the generated current within a selected period of time after the commencement of generation, the shunt and series field windings being in opposition. The diode is secured to a heat sink 76 Fig. 1 in turn secured to a plate 73 mounting brushes 70 which contact a commutator 59 connected to armature windings 58 disposed on polepieces 57 of laminated discs 56 secured to a portion of the engine crankshaft 20 provided with a flywheel 30. The series and shunt filed windings 64, 66 are carried by polepieces 61 in a yoke and housing 60. A manual starter 37 ... 42 is also provided, the invention being applicable to boat outboard engines 10 having one or more cylinders 17. |
