ESAW Motor Driven Van De Graaff Generator Small (E-6690)

Useful for electrostatcs experiments, where connuoussource of high voltage is needed. A motor driven assembly encased in a sturdy metal box made of specially designed two part aluminium extrusion with insulated plascside supports for safety. The motor driven lower roller rotates the upper roller assembly located on top of the insulated Perspex pipe through a removable flat rubber belt. The connnuousotataon of rubber belt results in accumulaonof charge on the one piece near spherical metallic dome, charge being transferred contnuously from rubber belt through charge collecting combs. Specially designed dome, with smooth and polished surface free of any surface imperfecons,and without any sharp corner or edge to minimize charge leakage. The motor operates on AC mains 220-240V, 50/60Hz, fused input through a 3- Core mains cable. Provided with indicator type ON/OFF switch. On bringing earthed discharge sphere, sufficiently close to the charged dome, transfer of charge from dome to the ground takes place in the form of electric spark jumping from dome to the discharge sphere. Under favourable condions,it can develop electric potenal upto 200kV, with a spark of upto 70mm length. 4mm socket terminal provided at the botom for earthing and another 4mm insert on top of the dome for charge transfer or ataching accessories.

Provides for necessary adjustment in all the cri al components.

Supplied complete with discharge sphere, mounted on a long insulated handle.
