Tetrix DC Drive Motor W739083 dynamometer data

[LH Machinist]

Thanks for the information. However, it doesn't make sense in my mechanical mind...using a 2 to 1 gear reduction with 4" wheels. An unloaded motor runs @ 178 RPM, (2.96 revolutions second) multiplying this by the circumference of a 4" wheel. 2.96 x 12.56 = 37.17 inches per second. Based upon the math and considering the load will reduce RPM, +/- 3 seconds is plausible.

If the RPM is reduced by 1/2. +/- 6 seconds seems like the time to reach the top.

Am I missing something?
