Motor Structural Casing ( EV2.2.1 )

[trip]

The new rule in the Electric Powertrain ( EV2.2.1 ) is not clear about having a complete casing around the motor or if you can have a casing just above the motor.

In case of having a complete casing, is necessary to have the motor's poles inside it or they can be outside ?

''EV2.1.2 Motors must be contained within a structural casing where the thickness is at least 3.0 mm (0.120
inch). The casing must use an Aluminum Alloy of at least 6061-T6 grade or better if a casing
thickness of 3.0mm is used. If lower grade alloys are used then the material must be thicker to
provide an equivalent strength. ''

Thank you for your help.

Casing above the motor, as in just like an access cover? As long as the rest of the housing that the motor sits in meets those same material specs I doubt it would be a problem, but the intent is obviously that the entire motor is housed in a structurally secured enclosure made of material at least 3.0MM thick and at least as strong as 6061-T6 aluminum.
