MOTCO " make DC Motors are available with different Performance
Characteristics and accordingly are classified into SHUNT / SERIES &
COMPOUND Motors.
DC
motors have definite applications in today's industry. Each type
offers specific characteristics and strengths, depending on the
task at hand.
Shunt
wound Motors are the most widely used as they have a linear
characteristic of Voltage & Torque.
* Shunt motor has more constant and controllable speed over
various loads.
Series
Wound Motors are used for High starting Torque
Applications.
* Series motor has greater torque capabilities
Compound
Wound Motors are used for Mixed Load Applications.
* The above two desirable characteristics can be found in the
same motor by placing both a Series field and Shunt field
winding on the same pole. Thus we have, the Compound motor.
* The Compound motor responds better to heavy load changes than
a Shunt motor because of the increased current through the
series field coils. This boosts the field strength, providing
added torque and speed. |
