Ballscrew System Vs Linear Motors

Siemens 1FN linear motors offer enhanced dynamic response and speed significantly. Velocities up to 300m/min and accelerations of up to 45g are theoritically possible. In practice, today's machines already reach feedrates of 100m/min and accellerations of 1.5g.

Following is the typical benchmark test result comparing ballscrew system and Siemens linear motor.
