A dual shaft gerotor motor ( 11 ) of the type comprising a gerotor gear set ( 13 ) including an internally-toothed ring member ( 15 ) and an externally-toothed star member ( 17 ). The motor ( 11 ) includes substantially identical first ( 25 ) and second ( 27 ) motor housing assemblies attached to first ( 21 ) and second ( 22 ) axially opposite ends of the gerotor gear set ( 13 ), and defining first ( 47 ) and second ( 45 ) fluid ports, respectively. Each of the motor housing assemblies defines a plurality N of fluid passages ( 65 ), each of which is in fluid communication with one of said fluid volume chambers ( 19 ) defined by the gerotor gear set ( 13 ). The first fluid port ( 47 ) comprises an inlet port and the first motor housing assembly ( 25 ) and the first valve means ( 37 ) cooperate to provide first commutating fluid communication from said inlet port ( 47 ) to said expanding fluid volume chambers ( 19 ). The second fluid port ( 45 ) comprises an outlet port and the second motor housing assembly ( 27 ) and the second valve means ( 37 ) cooperate to provide second commutating fluid communication from said contracting fluid volume chambers ( 19 ) to said outlet port ( 45 ).
