Features:
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 user 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.
Science School Basic Electronic Demo Motor Teaching Project
Permanent magnet DC motor model to DC electric motor, simple design easy to assemble and disassembled ideal for school scientific teaching project.
DC motor experiment: input 3V - 6V DC through wires and terminals, the coil will rotating, and speed up when voltage step up.
To avoid short circuit, two electric brush never touch the commutator segment.
