The Difference Between Motors and Generators

In the realm of industrial machinery, motors and generators are two electrical devices that are commonplace across many appliances and applications. While sharing similarities in hardware requirements and operations, motors and generators perform different functions. As the two may be used in the same setting, it is very important that one has a basic understanding of their distinct uses and differences.

When discussing electrical motors, one is referring to a device that is able to convert electrical energy into harnessable mechanical energy. Motors operate based on the principle of electromagnetism, which describes how electric current flowing through a coil will generate a magnetic field that can interact with the field of a permanent magnet. This process results in the rotation of a coil, which in turn drives a shaft so that desired work can be carried out. More than that, motors may come in a variety of types and designs, the most common on the market being DC, AC, and servo motors. 

On the other hand, generators are devices that convert a source of mechanical energy into electrical energy that can then be used. Generators perform their duties based on the principle of electromagnetic induction, where a changing magnetic field induces an electrical current in a conductor. With a standard generator, the design will consist of a rotating shaft that is attached to a coil of wire, that of which rotates within a magnetic field. As the coil is rotated, it will cut across the magnetic lines of force, producing a voltage that drives a current through the wire. 

With this basic understanding of both devices, one can see that the major difference between the two is the direction of energy flow. With a motor, electrical energy is transformed into mechanical energy that can be used to perform work, while in a generator, mechanical energy is converted into electrical energy. Another significant difference is the source of energy that is required to operate each device. With a motor, an electrical source will be necessary for the device to generate a magnetic field and create movement. Meanwhile, generators will require a mechanical power source so that the coil can be moved for magnetic field and electrical generation. 

Based on the mentioned operational differences, the application of each device will differ. For motors, common uses include within industrial machinery, electric vehicles, household appliances, and robots. In these settings, the motor will convert electrical energy into mechanical energy that can be used to drive a conveyor belt, pump water, turn a fan, or much more. With generators, electrical energy will be created within settings like a wind turbine, hydroelectric power plant, or internal combustion engine. With a better understanding of their differences and varied uses, you can hopefully best take advantage of such devices for your operations.
