Patent abstract
A method for controlling an electronically commutated DC motor is provided, the DC motor including at least one particularly permanent magnetic rotor and a wound stator, which is a drive motor for an adjuster device on a pneumatically operated disc brake. The rotor position is determined from electrically measured parameters without sensing of the rotor position. The invention is characterized in that two determination methods for determining the rotor position from electrically measured parameters are combined with each other, whereby one is an inductive measurement and a further one of the determination methods is a measurement of the inducted voltage.
