I don't know what exactly that all means. I couldn't imagine the max power is only 180 W for a motor of that size.
Check out my Technical Library. It's loaded with useful stuff. I should update it, since I have more. I'll have to talk to BM about that...
The link you need is under Mechanical - Motor Power.


Max Power = (115/2 RPM * 60/2 in-lbs * 0.0118) = 20.355W
Elec Power = 24V * 7.5A/2 = 90W

Unfortunately, those motors are far too weak to power a device such as a Segway. They aren't very efficient either...

For comparison, the CIM:
Max Power = (5342/2 RPM * 346.9/2 Oz-in * 0.00074) = 342.8W
Elec Power = 12V * 114A/2 = 685W

The Bosch Drill:
Max Power = (19,670/2 RPM * 0.870/2 N-m * 0.1047) = 447.0W
Elec Power = 12V * 127A/2 = 762W

The drill seems more powerful at first glance, but also it's extremely optimized for the forward direction. You can expect 15% less power when operating in reverse.
