Integrated-motor Rod-style Actuator

Aug. 16, 2011
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 is the largest and most powerful integrated-motor rod-style actuator the company makes and 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.
"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," says 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," says 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 VAC in any incremental stroke length from 6 inches to18 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.
