I don't think you understand the difference between these motors if you interpreted "magnet-free" as "magnetism free".

Renault has used two speeds in their electric race cars.
A "magnet-free" motor is a misnomer. All electric motors have magnets, even if they aren't rare-earth magnets or permanent magnets, they still have magnets.
A reluctance motor has stator poles that are permanent magnets. It also has a ferromagnetic rotor that has magnetic poles induced into it turning it into a magnet too.
