Electric motors are used in almost every industry and in a wide range of applications. Electric motors are available in a wide range of sizes and types. These motors can be selected based on their functioning, voltage, and applications. Using the proper motor with high-quality parts and performing regular maintenance keeps your motor running smoothly and protects endpoint equipment from wear and power spikes.

A dc motor, as we all know, is a motor that converts electrical energy into mechanical energy. We can utilise this motor in a variety of applications because of its energy. The application of several types of DC motors has been discussed in this blog.


Electric motor is a machine which converts electric energy into mechanical energy usually by employing electromagnetic phenomena. . It works on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force whose magnitude is determined by F = BIl Newton and whose direction is determined by Fleming’s Left-hand Rule. 

The various types of electric motor differ in the ways in which the conductors and the field are arranged and also in the control that can be exercised over mechanical output torque, speed, and position. The following are the two main types of electric motors:

  • AC motors, which are powered by alternating current
  • DC motors, which are powered by direct current

Electric motors are available in a wide range of sizes and types. These motors can be selected based on their functioning, voltage, and applications.


In DC Motors,Direct current electric energy is converted into mechanical rotational energy. You can also utilize the device in reverse to generate DC electrical power by turning a motor shaft (making the device function as a generator). The winding connections, in which how the two coils in the motor are coupled to each other, can be used to classify DC motors.

A magnetic field is formed in the stator of a DC motor when it is turned on. The field causes the rotor to rotate by attracting and repelling magnets on the rotor. The commutator, which is hooked to brushes connected to the power source, supplies current to the motor’s wire windings to keep the rotor revolving.


  • Permanent Magnet DC Motor (PMDC Motor)
  • Separately Excited DC Motor
  • Self Excited DC Motor
  • Shunt Wound DC Motor
  • Series Wound DC Motor
  • Compound Wound DC Motor
  • Short shunt DC Motor
  • Long shunt DC Motor
  • Differential Compound DC Motor


Permanent Magnet DC (PMDC) Motors are DC motors with permanent magnet poles. The field flux is created by a permanent magnet in the motor. The magnets are positioned on the inner circumference of the cylindrical steel stator and are radially magnetized. The magnetic flux is returned through the stator of the motor. The rotor has a DC armature with brushes and commutator segments.The applications are

  • Washer
  • Windshield wiper
  • Automobiles as a starter motor
  • Personal computer disc drives
  • Toys
  • Wheelchairs
  • Blowers in heater and air conditioners.

Application of DC Series motor

This motor has a straightforward design. It’s also simple to design and maintain. This motor is used in cheap toys and automotive applications because of its high starting torque.

  • Cranes
  • Air compressor
  • Lifts
  • Elevators
  • Winching system
  • Electric traction
  • Hair drier
  • Vacuum cleaner and in speed regulation application 
  • power tools
  • Sewing machine
  • Electric footing

Application of DC Shunt motor

We all know that Dc shunt motor provide constant speed. This type of motor is mostly used in the constant speed application from no load to full load. The applications are,

  • Wiper
  • Automatic windscreen
  • Drills
  • Conveyors
  • Fans
  • Boring mills
  • Shapers
  • Blowers
  • Spinning and weighing machine
  • Centrifugal pumps

Application of Compound DC motor

There are two types of compound DC motors, as previously stated. One is a Differential compound motor, while the other is a Cumulative compound motor. Because the differential compound motor raises its speed as the load increases, it has poor torque characteristics. As a result, this engine is unfit for any practical application.

On the other hand, the cumulative compound motor has high starting torque characteristics. Also, it has good speed regulation at high speed so it is widely used in,

  • Presses
  • Electric shovels
  • Reciprocating machine
  • Conveyors
  • Stamping machine
  • Elevators
  • Compressors
  • Rolling mills
  • Heavy planners

Application of Brushless DC motor

Brushless DC motors were founded with the aim of providing better performance in a smaller size than brushed DC motors. When compared to AC models, these motors are smaller. The lack of a commutator and a slip ring demands the use of a controller built in the electric motor.

As the brushless motor does not have any brushes, it has high efficiency, high speed and electronic control. Mostly this motor uses in the,

  • Hand held power tools
  • Consumer electronics
  • Heating and ventilation
  • for small cooling fans
  • Transport
  • Vehicles ranging from aircrafts to automobiles
  • For gramophone record in direct drive turntables
  • In computer peripherals like disk drives, printers etc
