Abstract
A power tool includes a motor with a flux ring. The flux ring includes a ring member with a first and second end. The ends are positioned with respect to one another such that the ends move towards and away from one another during compressing and expanding of the ring. At least one anchor is unitarily formed with the ring. A pair of magnets are coupled with unitarily formed anchors to couple the pair of magnets with the ring. The magnets are coupled with the ring such that the ring may be compressed and expanded with the magnets secured in the ring.
