Motorized Rotary Stage

The drive mechanism is worm and worm gear. The worm gear ratio is 120:1.

It provides 360° of rotation at a maximum speed of 75° per second.

The maximum load of this rotary table is 3 Kg.

This 39 mm diameter rotary actuator has a body weight of 0.4 Kg.

The resolution of 0.0015°  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 stage is compatible with OES' line of Motion Controllers..
