- Ultra-High Resolution
- Continuous Rotation Range
- New: M-038.PD with Novel Active Drive Concept
- Preloaded Worm Drive for Zero Backlash
- DC Motor, Stepper Motor and Manual Versions
- 30 mm ø Clear Aperture
M-038 rotation stages are equipped with worm wheel drives providing continuous rotation in both directions. An integrated spring preload eliminates backlash. The worm gear ratio is 180:1, corresponding to a turntable rotation of 2 ° per revolution of the drive shaft. Coarse position can be read from an adjustable scale ring on the outer edge of the turntable graduated in 2 degree increments and a drive shaft mounted indicator with 0.1 degree graduations. DC motor and stepper motor drives are available.
M-038.DG features a 3 Watt DC motor with 29.6:1 backlash free gearhead and a 2000 counts/ revolution encoder, mounted on the motor shaft. M-038.5S is equipped with a 5 phase stepper motor providing 2000 half-steps/ revolution.
The top model, M-038.PD, is equipped with a 30 Watt Active Drive DC motor providing 9 µrad minimum incremental motion and velocity to 90 deg/sec. The novel Active Drive concept features an integrated, high efficiency power amplifier and reduces overall system cost, because the stage can be driven directly from a PC-motor controller card (e.g. C-842).
