Application note 1 tCNOTION THE LINEAR MOTOR COMPANY INTRODUCTION How does a linear motor move over a curved track? A seemingly complicated question with straight forward answers. Where traditionally different motion systems can be used to follow up on a linear motion, Tecnotion develops curved magnet tracks. These tracks allow more complicated curved movements using a 'traditional' linear coil unit. Tecnotion developed the curved tracks to minimize force losses. Electromagnetic design provides low cogging, and by using the right algorithms, allow very smooth motion. Especially transport and packaging systems can benefit from a curved magnet track. Curved magnets enable the possibility to create a closed track entirely from direct drive linear motor parts. In particular systems with continuous flow and with more motors on one track can achieve higher efficiency using closed loop curved magnet tracks. CUSTOMIZABLE There are existing curved magnet designs at hand, specifying a radius and magnet track width. Large projects with curved magnet tracks are highly customizable thanks to these designs. Depending on specific customer requests, Tecnotion can adapt the design, radius and number of segments required to make any curved track. We will advise the correct radius depending on the coil unit needed. When the radius is too small or the motor is too long, movements will become unpredictably (side-to-side and/or force variations).

Application note 1 tCNOTIONTHE LINEAR MOTOR COMPANY ADVANTAGES A curved magnet iron core system provides unique characteristics. What advantages they provide for your system depends on what parts the curved magnet track replaces. There is no direct comparison to be made between any current system and the iron core on a curved magnet track. In short, the curved magnet track is • Cost effective and less complex to control by using one motion system to control all movements. • Delivers a higher continuous force than a moving magnet solution. • Maintenance friendly and mechanically simple...

Application note 1 tCNOTION THE LINEAR MOTOR COMPANY CONCLUSION With a curved magnet iron core system it is always important to pay close attention to radius related to motor length. A certain motor length is needed to provide force to the application. This motor length will be the deciding factor in the possible radius. TheTecnotion TM3 (51x91 mm WxH) can for instance be used on a track with a 300 mm outer radius. Small deviations can be made by choosing a different track width and making concessions on the motors' force. For full flexibility in movement a slide can be used to power the...
