|Continuous Force||9 N 〜 222 N|
* Small Footprint and cross section
* Lowest weight per unit length
* Simple design provides trouble-free, precision control
* Low cost
* High Acceleration of light loads
* High Speed
* Moving Forcer Assembly: The forcer is made up of an aluminum housing that contains the motor windings, lamination stacks, and permanent magnets. The active surface of the lamination is slotted to form teeth with a pitch of 1 mm. The ends of the coil are brought out to either a "D" connector or to flying leads. Mounting holes on the top surface of the forcer are for attaching the customer's payload. The forcer comes in different widths and lengths, depending on the required force. Multiple forcers can be supplied with a single platen to allow for independent moving heads.
* Long Stationary Platen: The platen is a precision ground steel bar or tube that is slotted to form 0.50 mm wide teeth on the surface. The bar is hard chrome plated and filled with epoxy to provide a flat air-bearing surface for the platen. The platen is available in widths from 31.8 mm to 76.2 mm. The length of the platen is a function of the stroke. Single piece platens are available as long as 3.6 m. For longer strokes the platens will be supplied in sections.
* Encoders: Non-contact magnetic or metal scale optical linear encoders with a reference mark for homing.. Typical encoder output is a quadrature square wave signals A and B but sinusoidal output is available as an option.
* Limit Switches: End of travel limit switches can be included at both ends of the stroke. The switches can be either active high (5V to 24V) or active low. The switches can be used to shut down the amplifier or to signal the controller that an error has occurred. The limit switches are typically an integral part of the encoder, but can be mounted separately if required.
* Cable Carriers: Cable guidance is achieved by using a cable carrier. Cable carriers are oversized to allow for routing of customers hoses and cables.
* Hard Stops: Hard stops are incorporated into the ends of the stage to prevent over travel damage in the event of servo system failure.
