this really cool. exciting!

Think those 20kw motors be ideal for mid drives?
Great subtitles to english!

I took half of hour to add English subtitles.

It seems that only the Tesla Roadster has an induction motor, instead the Model S has a DC brushless from what I know.

Currently it's mounted into a ElMoto frame, with the Curtis-1232SE controller (48V, 350A max phase current). The max battery current was about 254A, battery voltage dropped to around 41V with this current. So, the max power consumption seen as of today with this motor was about 10kW.

Here's a nice little read on the argument, Ideally the ultimate motor break through would be a magnet that can be electrically increased or decreased in flux strength but still retain a very strong magnetic flux under no volt condition's this could give high efficiency at start up torque and at full speed when torque lags and efficiency drops the induction feed back loop could boost torque and efficiency at the same time. Theres clearly room for improvement but where will it come from.
Edit
You could achieve this effect with two ac motors one Induction the other magent, bolted together and the controller could monitor both motors and fire the magnet up for start torque and bring in the Induction at a higher rpm so efficiency is boosted and speed capabilitys, giving my secrets away now.

Hybrid motors already exist that have just enough PM to enable cruising. Modern IPM motors are kinda replacing induction by getting the best of both worlds, with respect to sipping watts cruising at light loads, and using reluctance torque in the shape of the rotor iron around the magnets to deliver torque well beyond what the comparatively small magnets alone could offer.
