Abstract
A method of extending the lifetime of a rolling-element bearing of an electrical machine, the method including: a) defining a first set of control parameter values, b) estimating a first remaining useful life, RUL, of the rolling-element bearing, based on a signal that provides a measure of vibrations of the rolling-element bearing obtained when the electrical machine is controlled by the first set of control parameter values, c) changing at least one control parameter value in the first set of control parameter values to thereby obtain a second set of control parameter values, d) estimating a second RUL of the rolling-element bearing based on the signal, obtained when the electrical machine is controlled by the second set of control parameter values, e) comparing the first RUL with the second RUL, f) in case the second RUL is longer than the first RUL, replacing the control parameter values in the first set of control parameter values with those of the second set of control parameter values, and replacing the value of the first RUL with that of the second RUL, and g) repeating steps c)-f) over and over during operation of the electrical machine.
