Abstract
An insulator assembly for a stator assembly of an electric machine includes an annular ring attached to a stator core, and a plurality of coil separators supported by the annular ring and extending from the annular ring axially along a longitudinal axis. One of the coil separators is disposed between each adjacent pair of the coils to prevent contact between adjacent coils having a different electrical phase. The coil separators are slideably inserted between the adjacent pairs of coils, with the annular ring positioning and supporting the coil separators.
