CENCO® Motor-Driven Rotator with Digital Display

Our Best Rotator is Ideal for all your Rotary Motion Demonstrations

Precise, digital measurement allows you to monitor the motor speed, or measure the total revolutions in a time period you select.

Our premium motor driven rotator is packed with features:
Powerful-D.C. motor delivers 200-1800 rpm at max torque of .11Nm
Secure and Convenient-Keyless chuck accepts spindles 1.6mm to 9.5mm
Electronic Controls-Easily regulates motor functions and
Adjustable Angle-Motor mount rotates easily to any of four convenient positions.
A special guide pin locks it in place.


Choose the direction of rotation, either clockwise or counterclockwise rotation with the simple push of a “forward/reverse” button that is interlocked with the motor speed. A heavy-cast base provides nearly vibration-free operation, even with the heaviest objects.

Size: 28 x 28 x 11.5cm high, weight: 8.2kg. Operates on 120 VAC, 60Hz at 1 ampere, 1.8m cord.

Improve the resolution and control stability of the Motor Driven Rotor with this upgraded electronics package.

It includes advanced motor smoothing and a closed loop digital control system that actively monitors and controls the rotational speed of the motor, using the existing sensor system for detecting the motor speed.

The control range is 200-1800 rpm and the speed is controlled to within 5rpm at the lower end of the range and 10rpm at the upper end. Display the set speed and advance or reduce it by 1 rpm increments by using the up and down arrows.

You can also use the fast forward button to advance or reduce speed in 50 rpm increments. When the buttons are released, the display reverts to the current actual speed. The control system changes the motor speed to the new set value.

To upgrade your current Motor Driven Rotor with this electronics package, call Sargent-Welch for details.
