For electric cars, break-in the electric motor before
running the car. Break-in seats the commutator brushes and
lessens the friction between the armature shaft and the
bearings or bushings at both ends of the motor.
Answer
Honestly I'm not sure. I can tell you that with real cars, a brand new vehicle just off the lot has what is referred to a break - in period. This means that for the first 50 miles or so you shouldn't over drive the vehicle. This allows the engine to losen up mechanically before it is ready for more stress.

Do electric car motors have oil that has to be changed? How are they cooled - coolant? What maintenance is required for an electric motor?
Answer
Electric car motors need no coolant, no oil changes, spark plugs, tune-ups, emission checks, fluids, filters, NOTHING. No maintenance whatsoever. An electric motor has just one moving part, compared to hundreds of moving parts in a gas engine.

Think about the electric motor in your refrigerator - how it just runs and runs for years, or even decades, with no attention or maintenance at all. Would you want a gas engine in your refrigerator?

I drive a 30-year-old electric car - a Jet Electra Van. It's a very old car, so I have had to work on the brakes, body, and suspension. But not the electric motor. It has all the original drivetrain parts from 30 years ago - the motor has never needed any maintenance or repair at all. Ever.
