Industrial Motors And Generators - Types, Applications And Manufacturers

Mechanical energy is converted into electrical energy by a generator, whereas the motor does the opposite. It converts electrical energy into mechanical energy. Because of electromagnetic induction, both the devices work, which is when voltage is induced by a changing magnetic field. But, how is a motor different from a generator? The electric motors and generators are differentiated on various factors like the function of the motor and generator or main principle of working. It  also depends on the production or consumption of electricity, the existence of current in the winding.  Both motors and generators follow Fleming's rule. From the construction point of view, the motor and generator are almost similar, as both have stator and rotor.   

Electrical Motors

Ever since the invention of electricity, motor or electrical motor has brought one of the biggest advancements in the fields of technology and engineering. A motor is an electro-mechanical device that converts electrical energy into mechanical energy. Different types of motors are available that have been developed for different specific purposes. Motors can be classified into DC, AC and Special motors.

DC Motors and AC Motors

Permanent magnetics, shunt, series, and others are different types of direct current (DC) motors, while reluctance motors, synchronous machines, and others are different types of AC motors. The electrical motors commonly find their applications in OEM based products, conveyor systems, fans, industrial machineries, pumps, and compressors. Through integration of sensors and electronic hardware, AC and DC motors can be developed. These sensors offers predictive maintenance and reduces downtime during maintenance.

Given below are the main applications of the three types of DC motors.

Applications Of Different Types Of DC Motors

1. Series Motors

The series motors are used in cranes, vacuum cleaner, traction system, sewing machine and air compressors etc.

2. Shunt Motors

Different applications of DC shunt motor are in conveyors, lifts, centrifugal pumps, spinning machines, fans, lathe machines, blowers, weaving machines.

3. Compound Motors

Compound motors are used generally in shears, conveyors, presses, heavy planners, rolling mills, elevators.

Applications Of Different Types Of AC Motors

Used in a large variety of applications, alternating current (AC) motors are low-cost and high-efficiency mechanisms. Consisting of a copper wounded stator that is magnetically driven and a rotor mechanism, AC motors offer a simple design. Various types and categories of AC motors have applications wherever electrical appliances are utilized, from heavy industrial to household environments.

1. Synchronous Motors

Used in high-precision drill machines and similar devices, synchronous AC motors find their major applications in areas where accuracy is important. Some of them are electromechanical robots, timers, speed controllers, clocks, metering pumps, and other industrial processes.

2. Induction Motors

These are the most common types of AC motors used in daily life processes. Induction motors are mainly used in kitchen appliances, water pumps, automobiles, fans and air conditioners and in common industrial machinery like compressors and boiler pumps.

3. Linear Motors

Compared to the conventional AC motors, linear AC motors are quite different in terms of functional and operational characteristics. Linear AC motors are widely used in roller coasters, monorails, ground-based rails, magnetic levitation lines, and similar transportation machinery.
4. Adjustable Speed Motors

Applicable in cargo pumps, electrical power plants, marine and land machinery, and water cooling equipments.

5. Universal Motors

Useful in a wide range of applications like commercial drill machines, high-power engineering, railway traction mechanisms, vacuum cleaners, dryers, industrial and kitchen blenders, and trimmers.
