Tolomatic adds Roller-screw Option to its IMA

HAMEL, MN – Tolomatic’s integrated-motor rod-style actuator (IMA) is now capable of delivering up to 3,300 pounds of force when equipped with the new roller-screw option. The Tolomatic IMA incorporates a hollow core rotor and skewed motor windings into its unique servomotor design for an extremely compact package with increased dynamic performance and service life compared to traditional rod-style actuators. The IMA’s unique integrated motor design is well suited for applications such as pressing, clamping, valve control, spot welding and volumetric filling.

The hollow core rotor design allows the nut of the screw to pass inside the rotor to provide 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 to provide smoother, more efficient motion and improved force repeatability,” says Dietrich. The compact footprint and efficient operation of the IMA, combined with the flexibility of control from an electric actuator, makes the IMA a powerful and viable alternative for replacing fluid power cylinders, he says.

The Tolomatic IMA with the new roller-screw option can exert a force of up to 3,300 pounds and move a top speed of about 12 inches per second. The IMA is available with a choice of motor voltages 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 IMA has a patent-pending lead-screw lubrication system that allows easy re-lubrication without disassembly. Tolomatic’s sizing and selection software makes selecting an IMA easy. All orders are built-to-order and shipped with Tolomatic’s industry leading five-day delivery.
