Rear motor model

[Hessles]

I’ve recently had the rear motor inverter changed due to failure. The new inverter has a generic plate where the motor model is stamped. Is there another way to find out which motor I have without a time machine?

Is there another way to find out which motor I have without a time machine?

Open it up and look at the internals for any kind of indicator markings?
