A versatile laboratory unit used for spinning the Centrifugal Hoop (RA-10), and Stroboscope Discs (RA-21), each of which are accurately sized to fit our Rotator. Other devices such as a siren disc, color disc, or vibrating string can also be used.
The electronic speed control is set at the factory to cover a speed range of 0 to 5,000 RPM. The “On-Off” switch is integral with the potentiometer so that it always must start at low speed. A pilot light shows when power is on even though the shaft may not be rotating.
The motor may be clamped in a wide range of horizontal and vertical positions. The heavy cast iron 18 x 13 cm base makes a good stable foundation. The chuck, mandrel, support post and clamping screw are all made from stainless steel.
