>what could make such a design better than a traditional inductive motor
Traditional induction motors, compared to these with wound rotors, are heavier and bigger in size for the same power output, and have less efficiency especially at starting/low-speeds.
- sidewndr46 3y agothat is only true if you don't have a VFD. At that point you can basically get whatever you want out of them until they melt or blow out a bearing
