DC motor Vexta series

two-phase stepper

Velmex Stages including UnSlides®, BiSlides®, XSlides™ and Rotary Tables can be powered by electric motors. Velmex products are built motor-ready. Motors are an adder to the product. Customers may purchase the motors needed direct from Velmex or they can add their own. Most commonly used is a DC step motor although, gear motors, servo motors and high resolution step motors in AC and DC can run Velmex products. Step motors are preferred for incremental position or scanning when computer controlled motion is desired. They are beneficial for complex motion requirements of more than one distance interval and/or speed, for very fast or slow starts/stops and fast reversing. Velmex offers a variety of sizes and configurations of Step Motors all at fractional horsepower. Motors should be selected with sufficient minimum torque to reach the top speed required. Review the Step Motor Speed and Torque Charts under the specification section, review the attached pdf chart on Steps, Distance, Speed Calculations or consult with a Velmex Application Engineer to select the appropriate motor for the application. An electric stepper motor transfers rotational power into linear or rotary movement with the help of a driver/controller. Stepper motors control how far and how fast the movement. They are very accurate. One pulse of electricity to the motor turns it one step, thus the name. Stepper motors are ideal for short, quick moves which are used in many positioning and motion applications. They can: • Respond and accelerate quickly. • They have low rotor inertia that can get to speed quickly.
