No magnets doesn't mean no magnetic fields. I believe they were referring to permanent magnets. An electric motor without any magnetic fields would be a very odd device.

And a motor with a static magnetic field is just as weird.

Ion drive thrusters. Not sure how one would translate them into a car, although there have been some on model aircraft, but they are a type of motor with a static magnetic field.
