There are five basic approaches used within the industry to secure stators into housings:
- Bolt in – the stator is bolted or screwed in place
- Press fit – there is an interference fit by design and the stator is pressed into the housing.
- Heat shrink fit – the housing is heated to achieve a clearance fit. Then the stator is inserted.
- Adhesive bond – An adhesive is used to bond the stator to the housing
- Axial clamp – Either a full 360 degree ring or a few “servo clamps” apply axial pressure to the stator stack to hold it in place.
Celera Motion does not offer a bolt-in option or recommend a press fit installation. When designing the stator to housing interface, the expected torque loads and joint strengths of the different retention options should be taken into consideration.
