Electric motor

A stator for an electric motor for a washing machine or dryer or washer-dryer, comprising:

• a core of magnetically permeable material including an annular core ring and stator poles spaced around and extending radially outward from the core ring,
• a polymeric insulating structure surrounding the stator poles and comprising:
• a side at least partially covering an axially upper surface of the core ring,
• a cylindrical wall at least partially covering a radially inner surface of the core ring,
• and further comprising two or more fastener supports for receiving fasteners at a fastener receiving portion, to fasten the stator to a non-rotating bearing hub or tub or drum or bearing housing of said washing machine or dryer or washer-dryer, wherein each of said fastener supports comprises a pair of axially directed walls which project radially inward from the cylindrical wall to connect with the fastener receiving portion,
• the wherein the radial length of the axially directed walls may be between approximately ⅕th and 1/15th of the internal diameter of the core ring.

• wherein the fastener supports further comprise at least one axially directed intermediate wall located intermediate of the pair of walls, and
• wherein the fastener supports further comprise at least one circumferentially extending wall that intersects with the axially directed walls and axially directed intermediate walls.
