Electric machines with a transformer circuit topology, such as induction machines, induction doubly-fed electric machines, and induction or synchronous wound-rotor doubly-fed ( WRDF ) machines, exhibit very high bursts of torque because the emf-induced active current on either side of the transformer oppose each other and thus contribute nothing to the transformer coupled magnetic core flux density, which would otherwise lead to core saturation.

Now I'm just trying to figure it out . . . To my mind this is unexpected and new, and it's worth exploring all the possible advantages once you're convinced it's a real effect . " However, even if Perepiteia does not produce perpetual motion, Zahn still believes that the device could have considerable practical applications, noting that " There are an infinite number of induction machines in people's homes and everywhere around the world.
