Was looking for an electric motor to run a mill off dc, and came across these

30KW dc brushless motor and controller
High Efficiency +Very Compact 30KW BLDC Motor
Voltage 72V Efficiency >90%
Rated Power 30KW Peak Power 60KW
Speed 15000rpm Rated Torque 270N,m
Cooling Method Fan Cooling Weight 30KG
Dimension 190mm(L) x 180mm(W) x 50mm(H)
Weight 4.5KG
Features
Regenerative Braking
Long working life (>20,000 hours)
Low noise, high torque
Excellent performance characteristics
High efficiency (>90%)
High reliability
Rated voltage : 72V
Rated power : 30KW
Rated speed: 8000-15000 rpm
Stepless speed control, dual-direction

I was comparing it to a warp11 (ie trevs ute)
warp11 Rated Torque: 173 Lb Ft @ 72 Volts And 597 Amps (1442 RPM)
Rated Power: 58 HP @ @ 72 Volts And 597 Amps (1442 RPM)
Continuos RPM: 5,000
Max RPM: 8,000

173 Lb Ft = 234.55650535n/m

apart from the higher rpm (leave gearbox in and drive around in 2nd or 3rdgear??)

price pretty much on a par with warp11

Anyone seen anything like it before being used in elcars?
being brushless would be a major step up from the warp motor (trev seems to be getting 10K km per set from his)
plus it already has a controller (quality????) and inbuilt regen braking

seems almost too good
