Deluxe Wimshurst Machine
This Deluxe Wimhurst Machine is a hand cranked device that demonstrates static electricity. Relative to a Van de Graaf Generator, it produces higher current with lower voltage. Consists of two high resistance plastic disks of diameter 31.5cm approx, with equally spaced metal sectors. The discs are supported in two rigid upright supports, rotating in opposite directions with a hand crank. Provided with a system of induced charge collecting brushes, adjustable ball-ended electrodes and cylindrical Leyden jar capacitors for obtaining higher potential. Produces substantial opposite charges which are deposited in the capacitors and on metal spheres. A rapid sequence of sparks can be generated by lowering the system's capacitance. Also spelled Whimhurst.
Deluxe qualities include a robustly-constructed electrostatic generator with oversize, 31.5 cm discs, this high quality machine is a great performer. The rigid supports, machined from solid PVC, and the high quality bearing guarantee smooth running, even when the hand crank is turned vigorously. Wimshurst machines produce a larger charge flow than the Van de Graaff generators but at lower voltages. This unit reliably generates a 6cm spark. The generator is 43cm high, 45cm wide and 26cm deep. Weight is 3.4 kg. Includes manual. Ages 10+. Also contains a comprehensive activity manual. Great for classroom demonstrations.
