Answer / akash malhotra
The working principal of dc motor is based on faraday's law
of induction.
When a current carrying conductor is placed in magnatic
field it exprieance a torque.
Applications of dc motor are
toys,robotics,Lathes,Drills,Boring mills,Shapers,Spinning
and Weaving machines,Electric traction,Cranes,Elevators,HAir
compressor,Vacuum cleaner,Hair drier,Sewing machine
