As I mentioned earlier, NASA has not designed a motor for the spacecraft. They clearly thought that just like in toys, electricity would come and wheels would spin. For this, there is no motor in the wheels. There is no such electric vehicle! The motor is separate, albeit electric, and produces torque. The purpose of the motor is to produce torque, not to turn the wheel. Turning the wheel is the result of thork produced in motor.
On the other hand, since there is no motor, problems such as cooling the motor and lubrication problem are not mentioned at all.
All the angry globalists above say: "it has it, you must believe it". The argument? Evidence? "Well, we have some pictures". Hahaha! How funny!
