Abstract

Some of the embodiments provide a method comprising: during an operation phase, operating a rotating device at a first speed; during the operation phase, monitoring a first current consumed by the rotating device to operate at the first speed; comparing the first current to a second current measured during a calibration phase while rotating the device at a second speed, wherein the first speed is substantially equal to the second speed; and based on comparing the first current and the second current, predicting a possible failure of the rotating device.
