In Siemens linear motors the forces are directly transferred which results in the highest dynamic performance but at the same time with high precision - almost without play and without overshooting. All of this is achieved without the motor components being subject to mechanical wear and without jerky motion.

Siemens 1FN linear motors offer enhanced dynamic response and speed significantly. Velocities up to 370m/min and accelerations of up to 45g are theoretically possible. In practice, today's machines already reach feedrates of 100m/min and accelerations of 1.5g. Siemens 1FN linear motors offer:

• Outstanding dynamic response and very high traversing velocity due simple construction without transmission elements such as ballscrew drive, coupling or belt.
• Excellent precision due to the extensive avoidance of the elasticity effects, play friction as well as natural oscillation in the drive train. If suitable measuring systems are used and the temperature conditions are appropriate, the motors can be positioned in the nanometer range.
• Simple installation.
• Effective cooling design due to Thermo-Sandwich dual-circuit cooling system (integral in 1FN1, optional for 1FN3) permits both a thermal decoupling of the motor from the machine.

Available version:

1FN1 Series for driving light loads with uniform velocity upto 95 m/min, maximum force from 1720N to 14500N. The permissible temperature increase at the mechanical interface to the machine limited to 2K.

1FN3 Series for driving accelerating loads as a result of high ratio between peak and continuous loads. Velocity upto 370 m/min with maximum force from 550 to 20700N. The permissible temperature increase at the mechanical interface to the machine can be extended to 4K with optional cooling precision.
