In this exciting project, you will see how to build a mini brushed motor using just simple wire, magnets, and Lego. A basic commutator will be used to control the rotations and will test its ...

However, in this basic solution I do hope to give you a feel for why commutators are useful, so in steps 4 and 5 I will discuss how these four move sequences were built. The focus here will be on ...

DC motor principles. DC motors consist of rotor-mounted windings (armature) and stationary windings (field poles). In all DC motors, except permanent magnet motors, current must be conducted to the ...
