Description

Specification Material: ABS Plastic Color: As pictures shown Size: length 290* width 180* height 215mm Weight: 2400g Main Specifications 1. Output no-load voltage: when the rotor speed is 1200-1600 rpm, the AC and DC no-load voltage ≥ 8V. 2. Output load voltage: When the rotor speed is 1200~1600 rpm, a small bulb of 2.5V or 3.8V, 0.3A is inserted in series. 3. When the two brushes are placed on both sides of the commutator, the output is AC, and the output is DC when placed in the middle of the commutator. 4. The distance between rotor and pole shoe is ≥1.5mm, no collision and friction 5. The performance of the whole machine: shake for 2 minutes, the belt will not slip or loosen; the brush will not be deformed, shifted, or generate electricity normally.

Features

Users of the fantastic device are interested things:Learning about AC vs DC current and seeing a visual demonstration.They are sick of going through batteries or finding wall outlets to product electricity for their experiments.

This apparatus allows students to easily compare and contrast an AC generator and a DC generator. For demonstrating the basic structure of the AC-DC generator and working principle.

It is an excellent activity model for study of the generation of electric current. The generator produces AC/DC current simultaneously when the hand wheel is turned. The generation of the AC/DC voltage is represented by bulbs.

With AC/DC voltmeter/ammeter for easy comparison,A great DIY educational toy for kids and student to have a hands-on experience and the sense of achievement.

It's good physical teaching tools, easy to undestand and handle. Great experiment toy to help children learn the Electromagnetic Induction Principle, and cultivate kids interest in physics and science.
