STEP Lab Electrodynamic Test Systems

Based On Linear Motors

General Description

Linear actuator based on linear motors for tests on materials and products. Suitable for tests in force and position control.

Advantages

High dynamic performance thanks to small moving masses

Reduced maintenance thanks to the absence of a mechanical transmission

Efficient and very low power consumption thanks to the high efficiency of the electric motor and the absence of mechanical transmission

Wide range of use thanks to the wide range of velocity that can be managed from 0.01mm/s up to 2.000mm/s and 100mm of stroke

Simple installation thanks to the request of only one electric socket
