High availability fan system
First Claim
1. A fan motor assembly with integrated redundant availability, said fan motor assembly comprising:
- a fan motor subassembly comprising a first fan motor and a second fan motor;
a fan motor selector mechanism coupled to said fan motor subassembly, said fan motor selector mechanism configured to selectively couple said first fan motor or said second fan motor to a fan;
a control unit coupled to said fan motor selector mechanism, said control unit configured to control said fan motor selector mechanism such that either of said first fan motor and said second fan motor is selectively engaged to said fan.

Abstract
A fan motor assembly with integrated redundant availability is recited. The fan motor assembly can include a fan motor subassembly with a first fan motor and a second fan motor, and a fan motor selector mechanism coupled to the fan motor subassembly, so that the fan motor selector mechanism selectively couples the first fan motor or second fan motor to a fan. The fan motor assembly can also include a control unit coupled to the fan motor selector mechanism, wherein the control unit is configured to control the fan motor selector mechanism such that either of the first fan motor and second fan motor is selectively engaged to the fan.

15. A method for providing integrated redundant availability in a fan system, said method comprising:
-
providing a fan motor subassembly comprising a first fan motor receptacle having a first fan motor coupled thereto and a second fan motor receptacle having a second fan motor coupled thereto wherein said fan motor subassembly is disposed in an orientation for driving a fan with said first fan motor; monitoring a performance characteristic of said first fan motor; comparing a measured performance characteristic of said first fan motor with a specified fan motor performance requirement; and provided said measured performance characteristic of said first fan motor does not meet said specified fan motor performance requirement, automatically disposing said fan motor subassembly in an orientation for disengaging said first fan motor from said fan and engaging said fan with said second fan motor. - View Dependent Claims (16, 17, 18, 19)
