Most of the machines operate with the aid of motors and generators (Bloomfield 374). Their roles can be interchanged, a motor can be used as a generator, and a generator can work as a motor. Motors are devices that convert electrical energy to mechanical energy, while the generator converts kinetic energy into electrical energy. This is the case in industrial applications. Conveyor belts, rollers, and grinding machines utilize the rotating power from a motor. Generators are used in areas where there is no electricity (Bloomfield 388). Generators use sources of fuel such as diesel and oil to produce electricity. The generated electricity can be used as a source of energy or used as a backup source. During generation of electricity, magnetism plays a great role in generators. With respect to AC motors, current is supplied to the windings leading to a production of a torque on the windings. Torque is simply a rotating force, which is required to drive various shafts in machines for their operation. Given that AC current is used, the motor spins at the same rate of recurrence with the sine wave. The term is referred to as synchronous motors. However, these motors are not commonly used and this leaves room for the use of induction motors. Induction motor coils are supplied with current indirectly as opposed to the case of synchronous motors. The current is induced in the coils with the help of magnetism (Bloomfield 382). An AC motor consists of commutators, brushes, coils, and permanent magnets. The magnetic field is generated around the Stator coils and the magnetic field experiences counter force from the magnetic field of permanent magnets. This in turn rotates the shafts of the machines for their operation.
