Answer: B
Share your understanding of this question with the correct explanation.
The DC compound motors are generally cummulative compound.
In a DC compound motor, the field winding consists of both series and shunt windings. The cummulative compound configuration means that the series winding is aiding the flux produced by the shunt winding. As a result, the total field flux is the sum of the shunt and series fluxes, leading to an increase in the overall field strength.
The cummulative compound motors are designed to provide high starting torque and good speed regulation. The combination of shunt and series field windings allows the motor to have a relatively constant speed under varying load conditions.
Therefore, the correct answer is B: Cummulative compound.
