Integrated servomotor actuator

Tolomatic's IMA55 integrated motor-actuator is capable of delivering up to 3,000 pounds of force and is designed for use in high-duty-cycle industrial applications.

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

ā€œWith 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,ā€ said Aaron Dietrich, marketing manager, Tolomatic. ā€œThe IMA55 actuator, with its integrated servomotor, is also shorter for a given stroke length than other types of rod-style actuators.ā€

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. ā€œIn addition,ā€ said Dietrich, ā€œthe skewed stator windings minimize the cogging of the motor and provide more efficient motion with improved force repeatability.ā€ 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.
