🔍 Key Concepts

• Compound wound DC motor: has both a series field winding and a shunt field winding. • Difference between cumulative compounding and differential compounding in DC motors. • How direction of current in the series and shunt windings affects whether their magnetic fluxes add or subtract.

💭 Think About

• Ask yourself: in a cumulatively compounded motor, do we want the series field to strengthen or weaken the main shunt field as load increases? • Think about what happens to the total field flux when both windings support the same direction of magnetic field vs. when they oppose each other. • Match the idea of "cumulative" with whether effects are adding together or canceling out.

✅ Before You Answer

• Identify whether cumulative suggests field fluxes that are additive or subtractive. • Determine if additive flux comes from current flowing so the magnetic fields are in the same direction or in opposite directions. • Eliminate any options where the description of direction and the description of additive/subtractive flux do not logically match.

When a compound wound DC motor is cumulatively compounded, what does this mean?

The current flow direction in each series-field coil is in the opposite direction as the current flow direction in its corresponding shunt-field coil, in which case the field fluxes are additive.

The current flow direction in each series-field coil is in the opposite direction as the current flow direction in its corresponding shunt-field coil, in which case the field fluxes are subtractive.

The current flow direction in each series-field coil is in the same direction as the current flow direction in its corresponding shunt-field coil, in which case the field fluxes are subtractive.
