Abstract
A power tool includes a flux ring with an annular member. At least one molded magnet is received on the annular member. An anchor is on the annular member to retain the at least one magnet on the annular member. The anchor is unitarily formed with the annular member to receive the magnet. The anchor includes at least one bend with a reinforcement member at the at least one bend.
Claims27
A flux ring, comprising:
- an annular housing;
- at least one molded magnet received on said housing;
- and
- an anchor on said housing retaining said at least one magnet on said annular housing, said anchor unitarily formed with said housing and including a bend and a reinforcing member positioned at said bend.
