Assuming that a cumulatively compounded DC motor is fitted with interpoles and compensating windings, normally how is the direction of rotation in such a DC motor reversed?

🔍 Key Concepts

• Effect of reversing current in different windings of a DC motor (armature, series field, shunt field) • How torque direction in a DC motor depends on the relative direction of armature and field currents • Behavior of compounded motors with interpoles and compensating windings as a single magnetic system

💭 Think About

• Which parts of the motor must keep their magnetic relationship the same to maintain the same direction of torque? • If you reverse current in every winding that contributes to the main field and armature together, what happens to the direction of rotation? • In a cumulatively compounded motor, which winding(s) are effectively in series and act together as one path for current?

✅ Before You Answer

• Identify which windings together create the main magnetic field and which winding produces the armature reaction torque • Decide which single change will reverse the relative direction between armature current and the main field • Ensure that you are not reversing both sides of the torque-producing interaction at the same time, which would leave rotation unchanged
