A DC motor has its field windings or magnets in the stationary outer
case. These don't need much cooling. Most of the heat is generated
internally, in the brushes, commutator, and armature windings. These are
much harder to cool, as they are moving parts. For this reason, they are
usually air cooled.

AC motors are usually the reverse; the field is the rotating part, and
the windings are on the outside, where they don't move. Thus they are
often liquid cooled.

But in either case, electric motors don't generate anywhere near the
heat of gasoline engines. There simply isn't enough waste heat to heat a
car. And the heat they do give off is at a much lower temperature.
