I-FORCE Ironless Motor Positioners

Linear motor positioners are known by many names such as stages, tables and actuators. They all mean the same thing. Each positioner includes 4 main elements; the linear motor, the linear bearings, the linear encoder, and the mechanics consisting of the base, carriage plates, bumpers, brackets and cable track.

Trilogy has created positioners based around our Ironless motors. Each positioner includes everything needed for motion except the drive and controller. The principal design goal for these positioners is to achieve high performance at an economical cost while preserving design flexibility to accommodate customization. The positioners are designed to connect together using transition plates for XY or multi-axis configurations. None of the positioners are based upon aluminum extrusions. The list below compares the differences between Trilogy positioners and those based on aluminum extrusions. Other features are also discussed.

• Trilogy positioners use ground steel or aluminum bases for flatness and parallism. Aluminum extrusions often do not meet the accuracy requirements for straightness and flatness.
• Trilogy has single or dual bearing rail positioners to match the performance and cost requirements for each application.
• Every positioner includes a magnetic encoder for industrial environments or an optical encoder with resolutions down to 0.1um (0.000 04").
• Dual rail positioners have bellows as a standard option.
• Multiple carriages options are standard all positioner series.
• Base material is selected based on weight and rigidity. Base material of 0.375" or 0.500" aluminum and 0.500" ground steel are standard, no cost options for most positioners.
• Positioners have several cable track options to accommodate the customer payload tubes and cables along with Trilogy's motor and encoder cables.
• Trilogy maintains stock on all components so most orders are filled within 4-5 weeks
