Connecting the speed controller - part 1
The motor’s contacts are connected by a wire that is wrapped in a special way. When electricity flows through the wire, it creates a magnetic field that makes the shaft spin. The direction the shaft spins depends on which way the electricity flows. If you switch the wires, the shaft will just spin the other way, and nothing bad will happen. The plus (+) and minus (–) marks on the motor only show which way to connect it if you want the shaft to spin in a certain direction.
