1 Brochure September 25 linear motors FN/FN3

2 Overview Construction variants FN linear motors are available as single-sided or double-sided motors. Single-sided motors The single-sided version consists of a primary section with standard winding that is mounted parallel to the associated secondary section. Double-sided motors The secondary section of the double-sided version lies between two primary sections (one primary section with standard winding and one with complementary winding). The construction as double-sided motor is particularly suitable for applications with movable secondary section and small traversing paths with fast acceleration (e.g. non-circular machining). In combination with the SINMICS S2, FN/FN3 linear motors provide an optimally tuned linear direct drive system for the requirements of modern machine construction. The motors comprise a primary section and a secondary section with magnets made of rare-earth material. The primary section has fixed dimensions, while the secondary section is made up of individual elements (segments) to suit the required traversing range. Through parallel operation of the motors, feedrate force and length can be scaled beyond the available spectrum. Version for continuous load Benefits 7 Outstanding dynamic response and very high traversing velocity 7 Excellent precision 7 Simple installation 7 Drive components are free of wear thanks to contactless drive force transmission The main advantage of linear direct drive technology is the extensive avoidance of the effects of elasticity, play, and friction, as well as natural oscillation in the drive train. This results in a Technical specifications higher dynamic response and increased precision. If suitable measuring systems are used and the temperature conditions are appropriate, the motors can be positioned in the nanometer range. Design The simple mechanical construction without transmission elements, such as ballscrew, coupling or belt, enhances the reliability of the drive components. Heat loss occurs almost exclusively in the primary section and is dissipated via an integrated liquid cooling system. The Thermo- Sandwich dual-circuit cooling system (integral in FN, optional for FN3) permits both a thermal decoupling of the motor from the machine, and also a low-cost cooling concept. The stainless metal encapsulation of the primary section ensure the high mechanical ruggedness and resistance to soiling required for use in machine tools, as well as high resistance to corrosive liquids. In addition, the motor places minimal demands on the preparation of mounting surfaces thanks to the large air gap. The mounting tolerances for the air gap are ±.3 mm (.2 in). pplication FN linear motors Grinding Ultra-precision machining pplication FN3 linear motors Version for peak loads Used in connection with machine axes that are accelerated for a short time (e.g. S3 operation), or if high power is required for short intervals. Typical applications: High-dynamic and flexible machine tool construction Laser machining Handling Used in connection with machine axes with constant changing of acceleration (e.g. S operation), with high process/weight forces or in operation without water cooling. Typical applications: Non-circular machining Vertical axes without counterweight, quills Handling, cartesian robots The have an overload range available for acceleration processes. The maximum force F MX can only be utilized up to a maximum velocity v MX(FMX) ; up to velocity v MX(Frated), only the feedrate force F rated is available. F F F v F v F v 2 Siemens 25
