Device for positioning and affixing magnets to a magnetic yoke member of a motor

A device for positioning and affixing magnets to a magnetic yoke member of a motor, comprising:

• a nonmagnetic support adapted to receive the magnets, a shape of the nonmagnetic support complementary to a shape of the magnetic yoke member;
• a magnetic element adapted to hold the magnets in position on the nonmagnetic support, the magnetic element arranged on an opposite side of the nonmagnetic support than the magnets, the magnetic element adapted to exert a magnetic attraction on the magnets greater than a magnetic attraction exerted by the magnetic yoke member during positioning of the device with respect to the magnetic yoke member, the magnetic element is arranged as a lower part of a chassis, the chassis including vertical rods adapted to secure the magnetic element to an upper plate;
• an arrangement adapted to vary at least one of (a) the magnetic attraction of the magnetic yoke member on the magnets and (b) the magnetic attraction of the magnetic element on the magnets to render the magnetic attraction of the magnetic yoke member on the magnets greater than the magnetic attraction of the magnetic element on the magnets;
• and
• a housing vertically movable with respect to the chassis, the housing including an arrangement adapted to position the device on the magnetic yoke member during placement of the device on the magnetic yoke member, the housing adapted to rest against the magnetic yoke member.
