About This

• 100% Pure
• * This machine is used to teach the basic structure and working principle of AC and DC generators in junior high school physics and elementary school natural knowledge teaching.
• * This instrument is a permanent magnet, rotatable armature generator, composed of a stator, a rotor, brushes, a base plate and a manual mechanism.
• * When the rotor speed is 1200-1600/min, the output voltage of the machine, the no-load voltage is not less than 6V, and the load voltage is not less than 3V, 0.3A
• * It is composed of a permanent magnet and a pole whip. The magnet is made of two pieces of barium constant magnetic material. The red is the "N" pole and the blue is the "S" pole.
