Tolomatic IMA 55 integrated-motor rod-style actuator

Tolomatic’s larger version of its integrated-motor rod-style actuator is capable of delivering up to 13.3 kN of force with a standard ball screw at a top speed of 30 cm/s. 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 integrated motor design is suitable for applications such as pressing, clamping, valve control, spot welding and volumetric filling.

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 45 cm, compared to standard actuators, due to the elimination of a separate motor, motor mount and gearbox. In addition, skewed stator windings minimise the cogging of the motor and provide more efficient motion with improved force repeatability.

The IMA55 actuator is available with a choice of motor windings optimised for 230 or 460 VAC in any incremental stroke length from 15 cm to 45 cm. Built with Tolomatic’s Endurance Technology features for maximum durability and extended service life, the IMA55 actuator has a lead-screw lubrication system that allows relubrication without disassembly.
