- Winding looks great/ hand wound
- Unbelievable specs, however detailed enough to get my interest.
- 7kW@6000rpm continuous would make it possible to run single stage reduction.
- Weight 1.45kg. Anyone looking for a low weight build might be interested

Erpms at full power is unfortunately high, around 90krpm. Most EV controllers won't be able to drive it to the max but i guess the new generation VESC controllers would be a good match for it.

Another very sexy motor to add to my collection, don't mind if I do...

This would be so nice to try with a lightweight dual suspension mtb and left side direct drive.

Too bad i'm out of ebike $ for the year :wink:

I'm thinking a 1st stage down to the left side of the BB then another stage to the rear could get an easy 15:1 with no suspension loads into the motor. And giving a 35mph top speed.
I wonder how noisy they are?

 

[larsb]

I guess it's on the noisy side since it's so lightweight and probably easy to resonate.

Also IP30=no protection from water ingress. Not exactly a daily driver sort of motor.

It'll work, i drove an open revolt motor everyday, in summer and in winter on salted roads for years - eventually it died from corrosion but this use was extreme.
