Should this motor be required to operate in an open loop application, you can control it with a step and direction signal from a standard microstepping drive. The power is supplied to the 2 or 4 phase forcer winding via a flexible cable. The full step is .010" [250 microns] for a 2 phase forcer and it can be microstepped down to .00004" [1 micron].
By integrating an optional linear encoder onto the single-axis linear stepper motor stage the linear stepper motor operates closed loop, as a 2-phase brushless linear motor, when coupled with state-of-the-art motion control electronics package provided by H2W. This allows H2W's stage to achieve speeds and accelerations previously unachievable with a linear stepper motor.
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 low overall weight of the stage makes it ideal as a Y axis (top axis) in a multi-axis system. The lower moving mass of the stage allows for much higher accelerations of light payloads.
An optional cable carrier allows a high cycle count and is oversized to allow for passage of customer payload cables and hoses. The back of the cable carrier can be easily removed and reattached to route through additional cables.
