<p>1292041 Alternators having field windings JOSEPH LUCAS (INDUSTRIES) Ltd 5 Jan 1970 [13 Jan 1969] 1878/69 Heading H2A For a three-phase alternator, a full wave rectifier assembly comprises first and second arcuate conductive terminal plates 36, 35 each having first and second portions 36b, 36a, 35b, 35a spaced apart by an integral neck 36c, 35c; first and second diodes 43, 42 carried by the first plate first portion 36b and a third diode 41 carried by the first plate second portion 36a, the three diodes having their cathodes electrically connected to the first plate 36; fourth and fifth diodes 39, 38 carried by the second plate first portion 35b and a sixth diode 37 carried by the second plate second portion 35a, such diodes having their anodes electrically connected to the second plate 35; means, e.g. bolts 44 ... 47 physically interconnecting the two plates in insulated relationship with the first portion 36b, 35b of each plate 36, 35 positioned between the two portions 35b, 35a, 36b, 36a of the other plate 35, 36 whereby there are positioned adjacent each other the first and sixth diodes 43, 37, the second and fifth diodes 42, 38 and the third and fourth diodes 41, 39; and three conductive connectors 49, 51, 52 respectively interconnecting the anode of the first diode 43 and the cathode of the sixth diode 37, the anode of the second diode 42 and the cathode of the fifth diode 38, and the anode of the third diode 41 and the cathode of the fourth diode 39. The plates act as heat sinks and have passages through which cooling air may flow. The connectors also carry respective field diodes 53 ... 55, and form the rectifier connections to the stator phase windings of the bolts 44 ... 47 which secure the plates to the alternator frame 11, the bolts 44, 46 are also respectively connected to the plates 35, 36 and thereby form the positive and negative output terminals, the bolts 47 also secure a voltage regulator 56, and the bolt 45 is connected to the frame 11. Similar Specifications 1,292,042 and 1,292,043 are directed to the brushgear constructions.</p> |
