Electrical Engineering ⇒ Topic : Characteristics of Compound DC Motors

Compund motors Characteristics:-

• Variable speed.
• Adjustable varying speed.
• Starting torque high upto 450% depending upon the degree of compounding.
• Maximum momentary operating torque higher than shunt, motor utpo 350%
• Speed regulation : Varying, depending upon degree of compounding, upto 25-30%.
• Speed control : Usually not used but may be upto 125% by field control.
