Eldon enclosures are a Rittal clone but are less expensive. I also use Saginaw for NEMA 4 and 12. I haven't had any quality issues with either brand. Factorymation sells both of them.

I suspect you will also need to be concerned about the amount of heat that the motor will generate with all the starting and stopping. It will probably at least need a constant running cooling fan.
