Abstract
A method is provided for manufacturing an encapsulated magnet carrier by forming a wax pattern of the magnet carrier with an annular conducting ring annular chamber section, placing the conducting ring over the wax pattern in the annular chamber section, and forming an investment casting shell mold around the wax pattern and conducting ring. The magnet carrier is then cast with the conductor ring in place by pouring molten casting material into the mold, solidifying the casting material, and then separating the cast magnet carrier with the cast in place conductor ring from the surrounding mold.
Claims7
A method of manufacturing an encapsulated magnet carrier circumscribed about a carrier axis, said method comprising the steps of:
- forming a wax pattern of a magnet carrier having a cage section with an annular axially extending base wall section and at least an annular aft end wall section extending radially from the base wall section, an annular conducting ring annular chamber section that is bound by the base wall section and the end wall section, and a plurality of circumferentially located compartment sections that are bound by the annular chamber and the end wall section;
- placing a conducting ring over the wax pattern in the conducting ring annular chamber section;
- forming an investment casting shell mold around the wax pattern and conducting ring;
- and
- forming the cast magnet carrier with cast in place conductor ring by pouring molten casting material into mold, solidifying the casting material, and separating the cast magnet carrier with cast in place conductor ring from surrounding mold.
