Tolomatic’s new, larger version of its integrated motor rod-style actuator is capable of delivering up to 3,000 lbs (1360.8 kg) of force with a standard ball screw. The Tolomatic IMA55 actuator’s unique integrated motor design is well suited 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 18 inches (46 cm) 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 and provide more efficient motion with improved force repeatability, the company says.
