Flytec ultralight motor

[speedmd]

I came across this lightweight, relatively low RPM high power motor that looks promising for a mid drive build by flytec. Any one have experience adapting one.

Some specs.

Wow, this is probably the first spec I see that actually includes inductance

They have two models of motors, the HPD10 at a bit over 2000 euro and the HPD13.5 at just under 2500 euro. Both run 40-58V. Look to be Good power to weight.

The "support" kit ( controller, programmer, data logger, etc) .. all look interesting too..

not to mention some of the devices they fit it in !...

I recognize the design. It has been on the forum before. I remember a link to the original design paper or similar.

That's an interesting motor!

I like the "ergonomic" design of their PiWi controller!! 8)

Search for "Werner Eck"

I'm sure I've posted this before somewhere...

Hi Miles.

Thanks for the link. Copper ribbon wound! WOW! Looks like rectangular jumpers between them.

Only supported on one side like the joby and a out runner design. Not crazy about that driving a sprocket setup and side loading it. Looking forward to what you come up with in your large diameter inrunner design.
