H2W Technologies linear stepper motors are ideal for open loop positioning applications with light payloads. They can be used at speeds up to 80 in /sec [2 m/sec] and strokes up to 144” [3.6 m]. Linear stepper motors are capable of very precise position, velocity and acceleration control when coupled with a microstepping drive and indexer.The short moving assembly called a “forcer” is guided by either roller or air-bearings along he precision ground track called a “platen”. The bearings are designed to support the customer’s payload and to maintain the required .001” [0.025 mm] gap between the platen and the forcer.The step and direction signal from a microstepping drive, to the 2 or 4 phase forcer is supplied via a power cable. The motion achieved with a full step is .010” [250 microns] and with a microstep it’s .00004” [1 micron].The linear stepper motor is a complete positioning stage with the motor, the bearings and the positioning system all built into one compact package.Integrating a linear encoder with the stepper provides a closed loop system.Advantages:
