Hp, Torque, and RPM Capacity:*

*Actual air-cooled eddy-current capacities are RPM and rotor-temperature dependent. Initial cold torque and Hp limits are approximately twice their warm ones. (Hp ratings shown below taken after running 1+ minutes, at full load, in a room-temperature environment.) Continuous ratings are approximately 50% of warm values. See online load charts for curves.
“Micro” up to 1 Hp (warm) – ¼ Hp minimum*
“Mini” up to 3 Hp (warm) – ¾ Hp minimum*
#20 up to 20 Hp (warm)*
#100 up to 100 Hp (warm)*
#150 up to 150 Hp (warm)*
#300 up to 300 Hp (warm)*
#650 up to 650 Hp (warm)*
#1300 up to 1,300 Hp (warm)*
Hp options range from ¼ to over 10,000
Torque options range from ¼ to over 5,000 lb-ft
RPM options range from 500 to over 30,000
