The multiple linear motors share the same axes to provide performancewhilst saving machine space. The tubular linear motor is well balancedbecause the symmetrical design eliminates attractive forces, making mechanical integration simpler. Furthermore linear motors and actuatorsuse an integrated position sensor so no external encoder strip is required enabling two or more forcers to operate on the same magnetic rod. A dual forcer stage can provide independent control of both forcers,so that two independently controlled forcers can double productivityand independent motion becomes possible. The forcers can travel in unison or in opposite directions, so for example one linear motor can beprogrammed to load parts while the other unloads them. The efficient design of the ServoTube motor minimises heat dissipation, eliminating the need for forced air cooling. The linear motor is available in 25mmand 38mm diameter rod models, with different coil configurations to meet the required force and speed of the application.
