They're using a Synchronous Reluctance Internal Permanent Magnet (SRIPM) motor. Interesting that they see the value for money advantage DC presently holds will disappear in about 5 years, per this post on DIYelectriccar.com.

[ Edit: SRIPM seems to be a fancy name for the type of motor that is in many EVs and hybrids including the Prius 20 years ago, the "Interior Permanent Magnet" (IPM) motor. ]

Too bad, I just paid for my HPEVS AC51 two months ago and it was just delivered, I would have jumped on this at almost $2000 cheaper !! and the specs look better for my purpose !!

It looks quite nice.
But the whole system looks about AUD$7,200 landed for 100kW peak.
Which seems a tad over priced over a regular induction motor of similar spec.

The power graph for that suggests 1,200 RPM before it hits the voltage limit.
Seems quite low.

Perhaps this is so they can release a new controller later using the same motor that does 200kW at 2,500RPM :shock:
Now that'd be more like it :twisted:

I don't see a price anywhere for just the motor.

$5700 for the motor and controller at EV Works

$7,200 is buying it from a retailer in US, shipping, duty and taxes.
Even better that EV works list them for less.

But that controller is still underrated...
It's like the difference between a stock 4cyl lancer and V6 commodore in performance.
