摘要 |
A stator includes a housing made of magnetically conductive material, a plurality of magnets fixed to the stator housing; and a magnet holder attached to one end of the housing for fixing the magnets to the stator housing. The magnet holder includes a body and a plurality of locking structures extending from the body. Each magnet is locked between two adjacent locking structures. A plurality of cut-outs is formed in the stator housing, and a plurality of projections is formed on the body of the magnet holder and engaged with the cut-outs. Each locking structure includes a wedge-shaped inner end inwardly abutting against respective magnets to prevent the magnets from moving inwardly. |
