Tolomatic's integrated-motor rod-style actuator is capable of delivering up to 3,000 lb of force with a standard ball screw. The IMA55 actuator integrated motor design is well suited for applications, such as pressing, clamping, valve control, spot welding and volumetric filling, the company said

“With the addition of the IMA55 actuator to Tolomatic’s integrated-motor actuator line, we now have compact actuators for high-duty-cycle industrial applications that range in force from several hundred to 3,000 pounds,” said Aaron Dietrich, marketing manager, Tolomatic. “The IMA55 actuator, with its integrated servomotor, is also shorter for a given stroke length than other types of rod-style actuators.”

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,” said Dietrich, “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 V ac in any incremental stroke length from 6 inches to 18 in. 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, the company said.
