Abstract: An air mover may be provided. The air mover may comprise an air mover motor shaft, a bearing, a bearing housing, a circuit board, an accelerometer device, a temperature sensing device, and a controller. The air mover motor shaft may be associated with a motor. The bearing housing may support the bearing that supports rotation of the air mover motor shaft. The circuit board may be attached to the bearing housing. The accelerometer device may be disposed on the circuit board. The temperature sensing device may be disposed on the circuit board wherein the temperature sensing device may be located on the circuit board in order to obtain a temperature of the bearing housing. The controller may be disposed on the circuit board and may be operative to control the motor, collect vibration data from the accelerometer device, and collect temperature data from the temperature sensing device.

Abstract: According to one aspect, a method includes obtaining a first signal from a host at an air mover system, the air mover system including an air mover and a tachometer, the tachometer having an associated tachometer signal. The method also includes determining whether the first signal is a request for information associated with the air mover, and providing the information from the air mover system to the host on the associated tachometer signal when it is determined that the first signal is the request for information associated with the air mover.
