AC linear servomotor ServoRam

three-phase

The ServoRam is a servomotor that looks like a hydraulic ram. The only moving part is a cylinder, as it is in a rotary motor, but it moves freely along the axis of the motor instead of rotating, and the armature is fitted with a sliding seal to the outer tube, so that it also acts as a conventional piston. This unique and patented design allows powerful and rapidly changing electromagnetic forces to be directly superimposed upon quasi-static or gas spring forces, saving energy and simplifying many mechanisms. The innovative, award-winning, British machine is a dual-action, free-piston, linear, 3-phase, brushless servomotor. It is a force-generator that is scaleable from less than 1Kg to more than 100 Tonnes thrust, with piston travel distances from 10 mm to more than 100 metres and at velocities of more than 100 metres/second. The ServoRam is an ideal choice where high dynamic linear motion is required and is a clean alternative to hydraulic systems. ServoRams are fully compatible with Quin's range of PTS drives. The ServoRam is manufactured by Advanced Motion Controls more information is available at their website
