Learn about DC shunt motors for constant speed, DC series motors for variable speed, and DC compound motors for specific industrial uses such as lathes, drills, electric traction, elevators, and more.
E N D
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.
D.CSeries motor • It is a variable speed motor.The speed is low at high 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
D.C Compound motor • Differential compound motors are rarely used because of its poor torque characteristics. • Industrial uses: • PressesShears • Reciprocating machine.
