yeah, only a wag on my part but my coincidence meter went off-scale.
two companies, one in ventura, the other in santa barbara, two counties that border each other.
both producing similarly distinctive if not unique coreless BL motors located a stone's throw apart, what are the odds.


if not a disgruntled engineer, could simply be mil funding in the background but can't help feel there's some commonality at play.
both also targeting uav's.
LwM is co-located with and backed by the Toyon Research Corporation

So this motor doesn't have any backing iron?

Thingap, which has, seems a lot better, to me.
 
Yes I got that, but I mean, on the other side of the windings. There's nothing closing the magnetic loop, only air.
Backing iron is not the right word.
 
wow ! the power to weight ratio is amazing

It sure would help to judge, if everyone gave continuous ratings..........

model 6:

150mm diameter, 25mm axial length, ~4kW @ 6,000 rpm, under 1.5lbs active weight
4Kw at 6000rpm is 6.4NM

Typical specifications for the Model 6 include:

3.0 N-m @ 6,000 rpm
Kv =
Kt = 0.15 N-m/A
100v operation
peak torque / continuous torque ratio: 6:1 or greater
peak coil temperature: 150 degrees C
