Highest precision with electric rotary stages from norelem

In addition to the manual version, norelem now also offers a positioning rotary stage with coaxial electric drive.

Thanks to a digital control system, the versatile positioning systems from norelem enable angular positions to be precisely, quickly and repeatably set to within a hundredth of a millimetre. They are therefore suitable for use with handling systems, machine tools or measuring equipment.

Despite the motor, the electric positioning rotary stages from norelem are quiet and require little maintenance. The pre-tensioned worm gear operates with almost no backlash and the worm shaft bearing offers maximum radial rotation accuracy. Cables can be routed through the large hole in the hollow shaft. With the adjustable positioning ring, the rotation reference point can be set as desired to the position of the mounted component.

Both product families are compatible with the Nema 17 stepper motor and can be combined with all other positioning systems of the same size.

Positioning rotary stage with coaxial electric drive
At norelem, electric rotary stages are available in sizes 8 with gear ratio 40:1 and 12 with gear ratio 55:1. The maximum output torque is 1.2 Nm or 3 Nm. The products can be purchased without a motor, with a motor or with a motor and control unit. The cable outputs as well as the control orientation can be individually defined. There are a total of 18 versions to choose from. For a long service life, the housing and the turntable are made from anodised aluminium, the hollow shaft is stainless steel.

Positioning rotary stage with electric coaxial drive, high loading
Furthermore, norelem also has positioning rotary stages for high loads in its range, which meet the highest demands for speed and accuracy. In these angular design models, the bearing of the hollow shaft and turntable is effected by means of an axial needle bearing. The rotary stages for high loads are available exclusively in size 12 with gear ratios of 10:1 and 45:1, the output torque is 3 Nm.
