this is the 1930/8 turn motor:

It says "Power(Watts) @ Amps"
btw what’s the efficiency of the 1930/8 |
You can't equate torque with power. Watts is convertable to horsepower. IIRC, you can however calculate torque by using rpm and horsepower.
Oh, and the effiency of these motors depends on load and voltage. But you can see some graphs and data on
this page.
