Drive to optimise stepper motor performance
The ViX Microstepper is designed to optimise stepper motor performance across the speed range 0 to 50rev/s, and squeezes up to 200W shaft power from an industry standard NEMA34 frame stepper motor.
Digital servo boasts outstanding acceleration
The ViX series digital servo drive is available with power ratings of 250 or 500VA, giving continuous current ratings of 2.5 and 5.0A RMS with a motor bus voltage up to 80V DC.
The ET cylinder is typically fitted with stepper or servo motors to perform a variety of functions in material handling, machine tools and other industrial and laboratory applications.
The ET cylinders are available in ISO sizes 32, 50, 80, 100 and 125, with either in line or parallel motor mounting and IP65 versions are available which have the option of all stainless steel fixings.
Maximum thrust ratings range from 600N to 44kN (100km L10 life), and stroke lengths in the five sizes can be specified in millimetres and range from 50 to 750mm in the ET32 up to 100-2000mm in the ET125.
Typical repeatability is +/-0.013mm (+/-0.025mm on the ET125).
Each frame size of cylinder has the option of different pitch ballscrews.
Fine pitch screws (5mm per rev) give maximum thrust, whereas larger pitch screws allow speeds up to 1m/s.
Parallel mount units have a timing belt drive offering four drive ratios which further enables actuator duty to be matched to the optimum performance range of the attached motors.
The ET cylinder can be provided with motor mounts to suit a wide variety of third party motors and other nonstandard features are available on request, including C5 grade ballscrew, air purge fittings, oil baths for prolonged life in high duty applications, nonstandard screw pitches and preparations for aggressive environments.
