The invention is based on the discovery that modified calcium carbonates can be used as fillers for the preparation of non-abrasive adhesive formulations that are useful in microelectronic applications. To measure the rotational position and, where applicable, the number of revolutions of the rotor, the invention provides a resolver integrated in the canned motor which has a resolver rotor that rotates with the rotor and a stationary resolver stator, the cylindrical wall of the can also lying between the resolver rotor and the resolver stator. The mobile reader is configured to read a unique identification of an equipment unit and to determine a location of the equipment unit while proximate the equipment unit.
