Tolomatic's IMA Integrated Motor Actuator

The IMA is a rod-style electric actuator with an integratedservo motor. Motor windings are rated for 230 or 460V and are potted directlyinto the actuator housing. The actuator is capable of up to 2000lbs of peakthrust for ball screw versions and up to 3300 lbs of peak thrust for roller screw versions. The IMA, withits high and repeatable force, long life, smooth velocity and compact packagecan be used in a variety of industrial motion control applications as ahydraulic or pneumatic replacement. Applications include press fitting systems,valve/process control, spot welding, fluid dispensing and many others. TheIMA's integrated servo motor makes for a more compact package thantraditionally mounted motors, by eliminating the need for additional motorcouplers, adapters, belts and/or gears, thereby reducing assembly labor andparts sourcing. It is available with staggered connectors for convenientinstallation and wiring that emulates the most popular motor manufacturers forcompatibility out of the box. The smooth body design eliminates potentialcontaminant collection points. A variety of options including mounting and rodends, an electronic brake, and IP67 protection make it a flexible linear motionsolution. The IMA uses skewed motorwindings rather than segmented stators to reduce torque ripple and improverepeatability. The IMA motor incorporates a hollow corerotor design that further reduces actuator footprint by allowing the screw nutto pass inside the rotor. The screw is attached directly to the hollowcore rotor, eliminating motor couplers, reducing failure points, and improvingdynamic performance. A patent-pending grease port allows complete actuatorre-lubrication without removing it from fixtures for disassembly, savingdown-time and labor. The IMA has undergone 1.5 years of life testing (TolomaticEndurance Technology at work) to validate dynamic load rating capacities.
