Unfortunately switching the direction of current from a controller like the Omega is difficult. To get the motor to spin the other way, we need to reverse the applied voltage, meaning the flow of current through the motor will be reversed. The electromagnet is activated by applying voltage, so when the power is on, the magnetic field it generates will cause the armature (a coil of wire) to generate its own nagmetic field, these fields push eachother away and cause the armature to spin. The DC motor uses the uses a magnetic field generated by the by an electromagnet to turn the armature of a motor. A DC motor can change speend and direction depending on how much power is fed to it and in which direction. This kind of motor can be found in drones, power tools, and robots. The simplest of all motors, DC motors turn when a DC voltage is applied across it. Isolated Control with the Relay Expansion.Controlling a DC Motor using an H-Bridge.
