Abstract

A method for determining an effective resistance of a voltage controlled DC motor having a nominal resistance includes driving the DC motor with a signal so that the DC motor has a targeted acceleration, and sensing an effective acceleration of the DC motor. The effective resistance of the DC motor is determined as a function of the nominal resistance, the targeted acceleration and the effective acceleration.
