Hollow Cure Motorized Rotary Stage

Home > Motorized Rotary Stages

Hollow Core Motorized Horizontal Rotary Stage, Stage Diameter: 3.937 in (100 mm) 

This motorized rotary stage is made of aluminum alloy with an elegant black anodized surface.

The drive mechanism is worm and worm gear. The worm gear ratio is 180:1.

It provides 360 degrees  of continuous rotation.

The maximum load of this rotary table is 45 Kg.

This 100 mm diameter rotary actuator has a body weight of 1.7 Kg.

The resolution of +/-0.01 degrees   is achieved with a 10 micro-steps per step stepper motor driver. This rotation stage is also available with a servo motor and optical encoder.

The top plate mounted indicator shows the angle of rotation.

The knob mounted on the motor allows for manual adjustment. This knob may be replaced with an optical encoder for precision position verification.

This motorized stage is capable of continuous spinning.

This stage requires a Motion Controller that can be ordered as a complete plug-and-play system with RS-232, USB, joystick, trackball, and keypad control.
