" MOTCO " make DC Motors are available with different Performance Characteristics and are classified as below
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.
