You're right, we usually aren't getting the full power from these motors.

Each motor version (# turns) in a series, such as 1950 has the same peak power that is able to be extracted from them. It's just a matter of what configuration you want to run, higher voltage/lower amperage requirements, or lower voltage/higher amperage requirements. However, the higher voltage/higher turn setups USUALLY can extract a little more power than vise-a-versa, because of higher resistance losses, and hence more efficient.

One thing I notice with the Lehner motors is that the lower turn motors have great efficiency at higher torque's. Whereas, the higher turn motors have great efficiency at lower torque's, and slightly less efficiency than lower turn motors at higher torque's (a couple % points); BUT, overall the rpm range, they have a better average efficiency. It kinda depends on the application really. :030:
