ABSTRACT:
In one embodiment, the invention recites a fan motor assembly with integrated redundant availability. The fan motor assembly comprises a fan motor subassembly with a plurality of replaceable fan motors, and a fan motor selector mechanism coupled to the fan motor subassembly, so that the fan motor selector mechanism selectively engages one of the plurality of replaceable fan motors to a fan. The fan motor assembly further comprises a control unit which is coupled to the fan motor selector mechanism which is configured to control the fan motor selector mechanism such that a first replaceable fan motor mechanically powers the fan while a second replaceable fan motor can be dynamically removed from the fan motor subassembly.
