AIR GAP STABILIZATION IN VOLTAGE STATOR

摘要

AIR GAP STABILIZATION IN VOLTAGE STATOR Non-magnetic metallic spacers are welded into the auxiliary air gaps of a voltage stator using welding passes arranged in a predetermined sequence. The presence of the spacers stabilizes the auxiliary air gap against change in light load adjustment. Sequences of welding passes are disclosed effective for holding inherent light load error at nominal values, or biasing it positively or negatively.
