Electric drive system for mining haul truck

摘要

An electric drive system (300) for a vehicle (200) includes a first generator (306) in communication with a first engine (302), a second generator (308) in communication with a second engine (304), a first rectifier (310) and a second rectifier (312). Each generator (306, 308) has a main winding, each main winding being independently excitable and generating an alternating current (AC) output. A main AC output of the main winding of the first generator (306) is in communication with the first rectifier (310), and a main AC output of the main winding of the second generator (308) is in communication with the second rectifier (312). When in drive mode, the first engine (302) drives the first generator (306) and the second engine (304) drives the second generator (308), and the first and second generators (306, 308) supply power to a plurality of inverters (314, 316, 318, 320) coupled to the first and second rectifiers 310, 312), the plurality of inverters (314, 316, 318, 320) supplying power to a plurality of electric wheel motors (322, 324, 326, 328).
