The following sequential statements, when completed, describe
armature reaction
in a DC generator. Complete each statement by inserting the appropriate word from among those provided in the word list below.
Notes: A word may be used more than once. There are more words than required.
Word list:
armature, between, brushes, clockwise, commutator, currents, direction, distortion, increase, induces, inline, interpoles, main-field, neutral-plane, power, rotating, rotation, slip-rings, slow-down, sparking, speed, torque, voltage.
- The effects of armature reaction can be reduced by equipping the DC machine with _________________ connected in series with the _______________, or by physically shifting the position of the __________________.
- If this is not done _______________ will occur at the brushes and the generator output ________________ will be reduced.
- Prolonged operation in this state can lead to sustained damage to the brushes and _________________.
