IMA Linear Servo Actuators
The IMA linear servo actuator includes an integrated servo motor to simplify mechanical designs
The IMA linear servo actuator features a unique integrated motor design in a compact, industrial package. Available in both ball and roller screw configurations, the IMA actuators provide forces up to 8,044 lbf (35.8 kN) ideal for high duty cycle applications.
Ideal for dynamic applications or when the actuator is exposed to a high level of shock and vibration.
Drive Integration
Tolomatic’s integrated motor products (IMA & IMAS) integrate with a wide range manufacturers’ servo drives. Check our Drive Integration Resource for supporting documentation and motor files.
Tolomatic supports integration with Rockwell Automation through the use of custom motor files (CMF). See our Tech Note: interfacing the IMA actuator and absolute encoder with Rockwell Automation servo drives.
Flexible design with options to fit your application
All machines are different. Tolomatic offers a variety of options to ensure compatibility and fit with your machine. Explore our catalogue of options and accessories.
