Product Review

1. Introduction
This is a simple permanent magnet DC motor model to demonstrate the DC electric motor working principle. It can be taken apart and reassembled, when powered with 3-6V voltage (some clients may use 12V battery to test it, that is not advocated). It will rotate like a real electric motor ideal for school scientific projects or physics teaching.

2. Cautions:
① DC motor experiment: input 3V - 6V DC through wires and terminals, the coil will rotating, and speed up when voltage step up.
② To avoid short circuit, two electric brush never touch the commutator segment.
③ Permanent magnet: 22*20*20 mm (8.8*8*8 inch), Br ≥ 72 mT, N-pole is red, S-pole is white.

3. Warm Prompt ❤
This assemble kits are good quality. The English PDF instruction can be downloaded on this page and we also provide instruction in Chinese. If you need Chinese version, please email us. New batch has box packing, better than bags packing before.
