This can be when you'll be glad you taken out the air deflector tin. Never remove the bolt just nonetheless, just the nut.
The stationary armature may be wound for almost any effortless medium voltage amount, around tens of A large number of volts; manufacture of slip ring connections for more than a few thousand volts is high-priced and inconvenient. Cooling solutions
