Linear Motors

Siemens introduced its 1FN6 Linear Motors in three models that integrate with all Sinumerik or Simotion control systems using Sinamics drives. Linear scales for position and velocity feedback are available from a variety of third party suppliers to suit the application. The 1FN3 Peak Load Motors offer short time, high acceleration/deceleration and velocity rates comparable to S3 duty the company says. Suited to horizontal or compensated vertical axes, they possesses a nominal force (Fn) of 8,100N; maximum force (Fmax) of 20,700N and maximum velocity 253 m/min with liquid cooling. The 1FN3 Continuous Load Motors offer long power-on duration for horizontal, inclined or compensated vertical axes. Comparable to S1 duty, they have a Fn of 10,375N, Fmax of 17,610N and max velocity of 129 m/min with liquid cooling. The 1FN6 Magnet Free Secondary are designed for long traverse lengths at high acceleration and velocity rates. Suited to horizontal, inclined or compensated vertical axes, it has a Fn of 2,110N. Fmax of 8,080N and a maximum velocity of 532 m/min with air convection cooling.
