Integrated Servomotor Actuator delivers up to 3,000 lbf.
September 16, 2011 -
Optmized for dynamic performance and service life, IMA55 integrated-motor rod-style actuator delivers up to 3,000 lbf with standard ball screw. Hollow-core rotor design allows nut of screw to pass inside rotor, creating compact package. Additionally, skewed stator windings minimize cogging of motor and promote efficient motion with force repeatability. Able to move at top speed of ~12 ips, actuator comes with choice of motor windings for 230 or 460 Vac in any stroke length from 6-18 in.

New Tolomatic IMA55 Integrated Servomotor Actuator Delivers up to 3,000 Pounds of Force
Hamel, MN - Tolomatic's new, larger version of its integrated-motor rod-style actuator is capable of delivering up to 3,000 pounds of force with a standard ball screw. The Tolomatic IMA55 actuator delivers increased dynamic performance and longer service life compared to traditional rod-style actuators. The IMA55 actuator's unique integrated motor design is well suited for applications such as pressing, clamping, valve control, spot welding and volumetric filling.
The IMA55 actuator features a hollow-core rotor design that allows the nut of the screw to pass inside the rotor, creating a very compact package. This can decrease overall actuator length by as much as 18 inches compared to standard actuators due to the elimination of a separate motor, motor mount and gearbox. In addition, the skewed stator windings minimize the cogging of the motor and provide more efficient motion with improved force repeatability.
The Tolomatic IMA55 actuator with the standard ball-screw can exert a force of up to 3,000 pounds and move at a top speed of about 12 inches per second. The IMA55 actuator is available with a choice of motor windings optimized for 230 or 460 VAC in any incremental stroke length from 6 inches to 18 inches. Built with Tolomatic's Endurance Technology features for maximum durability and extended service life, the IMA55 actuator has a patent-pending lead-screw lubrication system that allows easy relubrication without disassembly. Tolomatic's sizing and selection software makes selecting an IMA55 actuator easy. All orders are built to order and shipped with Tolomatic's industry-leading five-day delivery.
