A fluid pump includes a pump housing having a housing cavity with an inlet and an outlet. An encapsulated stator assembly is positioned within the housing cavity and at least partially defines a fluid passage from the inlet to the outlet. A polymeric capsule member encloses and seals the encapsulate

A fluid pump includes a pump housing having a housing cavity with an inlet and an outlet. An encapsulated stator assembly is positioned within the housing cavity and at least partially defines a fluid passage from the inlet to the outlet. A polymeric capsule member encloses and seals the encapsulated stator assembly, protecting the motor from, and providing heat transfer to, the working fluid. A stator provides a magnetic field which drives a rotor assembly. The rotor assembly rotates an impeller for pumping fluid from the inlet to the outlet.

A method to stabilize a fan for cooling an engine driven welding machine generator, the method comprising the steps of: positioning a number of fins about at least one non-metallic fan segment such that adjacent fins have unequal spacing therebetween; providing mounting apertures having metallic inserts in the non-metallic fan segment; and connecting the at least one fan segment between a hub and a plate. 18. The method of claim 17 further including the steps of segmenting the at least one fan segment into a plurality of fan segments and concentrically positioning the plurality of fan segments around the hub with a given spacing therebetween. 19. The method of claim 18 wherein the plurality of fan segments are molded of an elastomer material. 20. The method of claim 17 further comprising positioning the fins of the at least one fan segment such that an inconsistent distance between fins results for at least three consecutive fins of at least one fan segment. 21. The method of claim 17 further including the step of integrally molding the fins and the at least one fan segment. 22. The method of claim 17 further including the step of essentially radially aligning the fins from a center of the hub. 23. The method of claim 17 further including the step of aligning each of the fins of the at least one fan segment at a common angle with respect to a base of the at least one fan segment. 24. The method of claim 17 wherein the plate has an aperture therethrough defining an inner edge of the plate and further including the step of abutting an annular lip of the hub to the inner edge of the plate. 25. The method of claim 17 further including the step of abutting an inner arcuate end of the at least one fan segment to the hub. 26. The method of claim 17 further including the step of providing a crush zone cushion in the non-metallic at least one fan segment.
