Abstract

A closed-loop motor speed control system is disclosed including a gerotor motor (11) having a gerotor gear set (51) operable to transmit rotational torque output by means of a main drive shaft (83) to an output shaft (13) by means of a set of splines (79) formed within a spool member (77). The spool member (77) and the housing section (49) cooperate to define a flow path from a fluid port (27) through the expanding and contracting volume chambers (67) of the gerotor (51), and to the fluid port (29). The motor (11) includes integral flow control capability. Rotation of a control shaft (43) and cam member (101) moves the spool member (77) from a position in which a passage (61) is in open communication with an annular groove (93) (FIG. 3) to a position in which such communication is restricted (FIG. 4).
