Malvern Handwheel Driving Unit for Energy Transfer Material_PVC adjustable resistance

adjustable resistance

5 inch diameter unit produces a +/-3mm controlled vibration on a string or ripple-tank dipper when driven by an external square-wave generator

and aluminum — sized to equal volume and drilled for suspension in calorimetry experiments

this resistor module on a demonstration base with 4mm plug connections drops into series with bulbs and LEDs in student circuits

Malvern Handwheel Driving Unit for Energy Transfer Material_PVC adjustable resistanceDrives Malvern dynamos, flywheels, pumps, and line shafts through a 16 by 16cm hand cranked unit with 75mm drive and output pulleys and a 3. 75: 1 step up ratio.
