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.
The small DC machines whose
ratings are in fractional kilowatt are mainly used as control device such in
Techno generators for speed sensing and in Servo motors for positioning and
tracking.
