M-037 Compact High Precision Rotary Table, Closed-Loop Servo Motor, Worm Gear

  • Ultra-High Resolution
  • Compact Design
  • Continuous Rotation Range
  • New: M-037.PD with Novel Active Drive Concept
  • Preloaded Worm Drive for Zero Backlash
  • DC Motor, Stepper Motor and Manual Versions
  • 20 mm ø Clear Aperture

 

M-037 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-037.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-037.5S is equipped with a 5 phase stepper motor providing 2000 half-steps/ revolution.

The top model, M-037.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 servo amplifier and reduces overall system cost, because the stage can be driven directly from a PC-motor controller card (e.g. C-842).
