Abstract
A medical, motor-operated or hand-operated or operable instrument includes a number of bearings for supporting a shaft for applying torque to a tool, of which bearings at least two selected or selectable bearings form a bearing pair. A distance sleeve axially spaces apart the bearings of the bearing pair. The instrument includes a component located at least partly radially inside the distance sleeve. The component is or can be rotationally coupled to at least one of the two bearings to rotate together with a rotating part of the at least one of the two bearings, or to form a rotating part of the at least one of the two bearings. At least one permanent magnet is fastened or formed on or in the component. A coil is arranged on or in the distance sleeve.
