1. D.C Shunt Motors:
It is a constant speed motor.Where the speed is required to remain almost constant from noload to full load.Where the load has to be driven at a number of speeds and any one of which is nearly constant.
Industrial use:
- Lathes
- Drills
- Boring mills
- Shapers
- Spinning and Weaving machines.
2. D.C Series motor:
It is a variable speed motor.The speed is low at high Page on torque at light or no load ,the motor speed attains dangerously high speed.The motor has a high starting torque.(elevators,electric traction)
Industrial Uses:
- Electric traction
- Cranes
- Elevators
- Air compressor
- Vacuum cleaner
- Hair drier
- Sewing machine
3. D.C Compound motor : Differential compound motors are rarely used because of its poor torque characteristics.
Industrial uses:
- Presses Shears
- Reciprocating machine.

Applications of DC Motors
The main applications of the three types of direct current motors are given below.
Series Motors
The series DC motors are used where high starting torque is required, and variations in speed are possible. For example – the series motors are used in Traction system, Cranes, air compressors, Vaccum Cleaner, Sewing machine, etc.
Shunt Motors
The shunt motors are used where constant speed is required and starting conditions are not severe. The various applications of DC shunt motor are in Lathe Machines, Centrifugal Pumps, Fans, Blowers, Conveyors, Lifts, Weaving Machine, Spinning machines, etc.
Compound Motors
The compound motors are used where higher starting torque and fairly constant speed is required. The examples of usage of compound motors are in Presses, Shears, Conveyors, Elevators, Rolling Mills, Heavy Planners, etc.
