1FN3 peak-load motors have short-time, high-acceleration/deceleration, and velocity rates comparable to S3 duty and are for horizontal or compensated vertical axes. The motors feature 8,100-N nominal force, 20,700-N maximum force, and 253 m/min maximum velocity with liquid cooling. 1FN3 continuous-load motors have long power-on duration for horizontal, inclined, or compensated vertical axes. They feature 10,375-N nominal force, 17,610-N maximum force, and 129 m/min maximum velocity with liquid cooling.
The 1FN6 magnet-free secondary motors are for long traverse lengths at high acceleration and velocity rates. They are for horizontal, inclined, or compensated vertical axes and feature 2,110-N nominal force, 8,080-N maximum force, and 532 m/min maximum velocity with air-convection cooling.
