10 lb Single Axis Linear Stepper Forcer, STS-1220-A4U
The STS-1220-A4U is a 4-phase single axis linear stepper motor that generates a continuous force of 11.0 lbs [48.8 N]. It is guided by precision roller bearings along the platen. Integral air bearings are used to maintain the required motor air gap. 60 PSI of filtered compressed air should be supplied by the customer. Power is supplied to the motor via a 9-pin D-Sub Male connector. There are mounting holes on the top of forcer to allow for payload mounting.  This is a replacement for Baldor / NorMag (Northern Magnetics) P/N 1304-2-B3.

This forcer is designed to operate on a 1.96" [49.8 mm] wide, 0.47" [11.9 mm] thick bar platen. Platen Model #: STP-20-XXX-A.
