My experience lately. My stepper driven router runs on 75V, I recently decided to try a servo on Z. Unfortunately it has a 60V continuous rating so I wrapped an external winding around the toroid to reduce down to 60V DC output. Before, all axis would run at 5m/min - after X&Y steppers would lock at anything over 3.8m/min so the servo came back off, as did the extra winding and it's back to 5m/min.
