Abstract: An automatic lubricator for lubricating an object is described, which comprises a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further comprises an electric motor configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action, and a control circuitry for controlling the electric motor. Therein, the control circuitry is configured to determine a back electromotive force, BEMF, generated by the electric motor during at least a part of the at least one lubrication action, and to determine, based on the determined BEMF, at least one lubrication parameter indicative of the at least one lubrication action.
