Is it normal for the motor to turn on when charging?
After charging for about 30 minute, the motor turned on.
This is only the second time for charging the car & the motor did not come on during charging.
The car is in the garage & it is a very hot day.

The motor(s) are only used to drive the wheels - so unless your car was actually moving, most likely what you heard was a cooling system maintaining the battery temperature. And yes, normal.
