Electro-mechanical actuators offer flexibility

Paul Boughton

The new I-Series of electro-mechanical actuators from Exlar offer users the combination of the highest levels of reliability – from Exlar’s roller screw technology, and complete flexibility in the choice of motor drive type, motor supplier, input transmission technology and mounting configurations.

The advanced I-Series electromechanical actuators are a clean, fast, simple and
cost- effective replacement for hydraulic actuation and provide a simpler, longer life alternative to pneumatic cylinders. They integrate Exlar’s inverted roller screw mechanism, a technology that enables Exlar to provide some of the most reliable,
long-lasting electro-mechanical actuators on the market.

The planetary design of the roller screws allows them to be accelerated and rotated faster than comparably sized ball screws, while their large contact area allows high force characteristics, and provides long life – typically 15 times that of comparably sized ball screws – even in the most demanding repetitive applications:

The I-Series is offered in several mechanical configurations to enable the OEM and user to optimise the performance and system cost to their requirements.

Rated to IP54 and supplied with an anodised coating, the IM Series offers mechanical capacity suitable for the lower forces and cycle rates achievable by stepper, dc, and ac motors, and is available at a proportionately lower cost. The higher specification IX-Series offers standard IP65 ingress protection and anodised coating.

Electroless Nickel and hard coating available as options. It provides maximum capacity to utilise the full performance of Exlar’s high torque density brushless motors, or the brushless motors from any manufacturer, for rapid cycling applications requiring long life.
