Abstract
A device for positioning and affixing magnets on a magnetic yoke member of an electric motor includes: a nonmagnetic support for receiving the magnets; a magnetic element for holding the magnets in position on the nonmagnetic support arranged on the other side of the nonmagnetic support with respect to the magnets, the attraction exerted by this element on the magnets greater than that exerted by the magnetic yoke member during positioning of the device with respect to the yoke; a device for varying the magnetic forces present, whereby the magnetic attraction of the magnetic yoke member and/or the magnetic element on the magnets may be varied such that the magnetic force of attraction exerted by the yoke on the magnets becomes greater than that exerted by the magnetic element on them, thus provoking transfer of the magnets to the yoke.
