Integrated servo motor actuator


The new integrated-motor actuator (IMA) from Tolomatic, Inc., combines a servo motor with Tolomatic’s proven rod-style actuator to provide a compact package. Compared to traditional rod-style actuators, the IMA’s integrated design provides higher dynamic performance by eliminating the need for separate motors, couplers, motor mounts, gearing and belts. The result is reduced component costs, assembly time and failure points.
“The IMA’s compact footprint, combined with the energy savings and flexibility of control from an electric actuator, makes the IMA a powerful, viable alternative for replacing pneumatic or hydraulic cylinders,” says Aaron Dietrich, electric product manager, Tolomatic. The high-force design of the IMA allows it to be used in a variety of applications such as pressing, clamping, valve control, spot welding and volumetric filling. The Tolomatic IMA provides high force (up to 2000 lbf) along with high speed (23 in./sec.) and positional accuracy (+/- 0.00984 in. or +/- 0.25 mm). The IMA can be ordered in any incremental stroke length from 6 to 18 inches.
Built with Tolomatic’s Endurance Technology features for maximum durability and extended service life, the IMA is offered with multiple ball screw leads, and a choice of motor winding voltages. The patent-pending screw lubrication system allows for easy re-lubrication without disassembly for extremely long service life.
