A method for prolonging service life of a bearing in a powertrain comprising an electrical machine, the method being performed in a control device controlling operation of the powertrain, the method comprising: detecting that at least one feature of a signal of the electrical machine violates a threshold limit, and determining a new operating area for the electrical machine in response to the detecting that the at least one feature violates the threshold limit. The control device may alter operating conditions of the electrical machine to be within the new operating area.
