Mounting Stators In Electric Motors

Using Tolerance Rings to mount stators in electric motors:

Mounting a motor stator assembly in an aluminum housing can be difficult, especially when there is thermal expansion and contraction expected during the electric motor’s life cycle. The stator core laminates can be fragile or brittle and any excessive force concentrations during assembly or thermal cycling can result in fragmentation and particle generation. Tolerance rings can reduce these concerns by compensating for thermal movements with their spring like characteristics, creating a uniform force distribution around the core’s circumference and allowing for proper axially positioning.
