Motors, Solenoids, Driver Boards/Modules

Motors are machinery that transforms electrical energy into mechanical energy. They work by creating force in the form of torque applied to the motor shaft through the interaction of the magnetic field of the motor and electric current in a wire winding. Direct current (DC) from a battery or alternating current (AC) from the electrical grid or an electrical generator can both be used to power motors. A solenoid is a machine made of housing, a coil of wire, and a moveable plunger (armature). A magnetic field that forms around the coil when an electrical current is applied pulls the plunger in. A solenoid, to put it simply, transforms electrical energy into mechanical work. Electrical energy is converted into rotational and linear force (or motion) by motors and solenoids, respectively.
