High speed motor for use with Gecko 340 Drive?

Hello Everyone,

I have an application that I am interested in using the 340 drive in.

I would like to find a motor capable of ~5000 RPM with the highest
amount of torque possible in a
certain package size. The motor diameter can not be much more than
3.15" and is limited to 8 inches
in length including encoder.

The project budget can support buying a new off the shelf motor so a
surplus source isn?t absolutely necessary. Any ideas?

Sincerely,

Paul.
