ABSTRACT:
A metal coil carrier fixture for mounting an annular field coil has a base and a lid separate from the base. The base has an upstanding tubular wall, a lower annular flange connected to, extending about and projecting outwardly from the tubular wall, and an upper wall disposed within and extending across the tubular wall and connected to an upper edge thereof. The lid has an inner central portion disposed in a substantially flush engaging relation with the upper wall of the base and detachably attached thereto, and an outer annular portion defining an upper annular flange extending about and projecting outwardly from the tubular base wall and spaced above the lower annular flange thereof when the lid is attached on the base. The tubular wall and lower annular flange of the base and the upper annular flange of the lid define an external cavity in which the annular field coil can be confined about the exterior of the tubular base wall and between the lower and upper annular flanges of the respective base and lid and into the from which the field coil can be inserted and removed by detachment of the lid from the base.
