Abstract
An electrical motor activation method for an electric motor including a rotor, connected to a motor shaft, and a stator having brushes. The stator comprises multiple commutator laminations for the commutation of windings disposed on the rotor and is activated by a pulsed or linearly controllable power source. The motor shaft is connected to a radially driven load, in particular a pump, which has a nonlinear torque curve via a motor revolution. A waviness signal is obtained from a voltage potential applied to the motor and/or from the motor current and rotor position information is obtained from the curve of said waviness signal.
