▎ 摘　　要

NOVELTY - The device has a magnetic element (26) and a holding element (24). The holding element is designed to protect the magnetic element. The holding element has a fiber (40a) or a yarn (28) which essentially consists of graphene or nanotubes. The magnetic elements are held by a single fiber or a single yarn. The holding element is designed as a sleeve element (38a). The magnetic element is designed as a permanently excited magnetic element or as an electrically excitable magnetic element. The magnetic element has a groove in which the holding element is partially received. USE - Holding device of rotor for electric motor or generator, e.g. for brushless direct current (DC) motor (all claimed) used as drive motor for hand machine tool, for electromechanical tool, for actuator for windshield wiper, window, seat, and pump for suction device, for vehicle, bicycle, household appliance, fan and toy and handheld power tool designed as mains handheld power tool or as cordless handheld power tool such as screwdriver, drill, hammer drill, hammer, saw, milling machine, grinding machine, multifunction device, and gardening implement. ADVANTAGE - The effective protection of the magnetic element is realized. The assembly of the electric motor is significantly simplified. The fixation is achieved, for example, by gluing, jamming, knotting, or welding, such as by an ultrasonic welding process. The compact electric motor is implemented. The compact and light electric motor is realized. The fastening of the holding element to the magnetic element is improved. The thin holding elements are realized, by using graphene or carbon nanotubes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for armoring a rotor of a brushless DC motor. DESCRIPTION OF DRAWING(S) - The drawings show a perspective view of a holding device, and a schematic view of a manufacturing method of the holding device.
