this motor is amazing it has a permanent on the rotor and armature coil on stationary part....this motor is a lot more efficient than the non permanent magnet motor ....but makes a loud noise at starting ....or the initial part.....or while delivering some serious torque ...i have seen this motor by some youtubers (EV west) they have done some good work on it
this guy had explain it in much better way
and ev west has a motor on there site you should give a try...thy also have some nice stuff on there website

The long awaited AC motor from NetGain is here. The new 9 inch HyPer9 AC motor is based on a new high efficiency design. The motor is a permanent magnet assisted synchronous reluctance design and holds the highest efficiency rating of IE4+ at 94% motor efficiency. The motor is IP67 sealed. The matching controller, an AC-X1 by SME Group will accept a supply side DC voltage of up to 132 Volts, and will output up to 760 Amps output, with a peak 88kW of power. The permanent magnets are a new design that are manufactured without the use of rare earth elements, but still gain a big efficiency advantage with a powerful 173 lb/ft of torque.
We are currently accepting pre-order reservations for this system. We are expecting to ship the first week of November.
