PRI In-Vacuum Motion Systems

In-Vacuum Motion Systems

Princeton Research Instruments, Inc. offers miniature in-vacuum stepper motors, motorized stages, and accessories that provide rotary or translation motion in high and ultra high vacuum without the use of mechanical feedthroughs. These products provide a unique, efficient alternative to the traditional mechanical feedthroughs. A full line of accessories is available including couplings, clamps, cables, electrical feedthroughs, etc.

STEPPER MOTOR HIGHLIGHTS: Motor Details

Motor operation in vacuum as low as 4 X 10^-10torr.
Maximum bake out and operating temperature is 150°C
Motor lifetime is measured in tens of millions of revolutions.
Variable reluctance design: no permanent magnets are used.
The motors can be placed anywhere, thus permitting compound motions that would otherwise be impossible.
Cryogenic operation is possible with specially prepared motors.
The motors and motorized slides can be quickly and easily relocated to suit experimental needs.

MOTORIZED SLIDE HIGHLIGHTS: Slide Details

Stock models have 1", 2" and 3" travel. Other sizes are available.
Slides can be compounded for X-Y-Z operation.
Standard stage step sizes are 3.3 microns, 1.6 micron, and .33 microns.
Cryogenic operation is possible with specially prepared stages.
Standard stages are aluminum. Other materials are available.
Wide selection of lead screws and gearing are stocked for custom designs.

MODEL SK-1 STEPPER DRIVER ELECTRONICS HIGHLIGHTS:

Stand-alone self-powered unit: no PC required.
Designed for the special requirements of in-vacuum stepper motors.
Design features help reduce waste heat buildup in the motors.
Half step, single step, or dual phase modes, speeds up to 1000 pulses per second.
Shaft position can be monitored with a digital counter on the front panel.
Accepts TTL logic inputs for remote or computer control.
