Sort of. Unlike gas motors which get part of their mechanical advantage from the angular momentum of the flywheel, electric motors have a torque that is strictly proportional to the current through the coils.
AC motors (like the ones Tesla use), work by pushing a sinusoidal wave around the "outside" of the stator, while a similar sinusoidal wave (at a retarded phase) is run inside the stator. This creates a magnetic field which is "ahead" of the stator's field (well in forward mode) which "pulls" it toward the field. The torque curve is "constant" and the speed is limited only by how well you can modulate that voltage. (and of course the mechanical construction)
