Discuss Bill Compton's answer to: Physics

why is a compound wound DC motor so named?

DC motors exist in these variants:

Shaded Pole (a magnet induces AC or DC to a three-coil armature and causes revolution. These are small motors, used to drive fans and analog clocks, etc.

Series Wound Universal. The field winding is wound one way and the armature is wound oppositely. These motors are typically used in high-torque/short duration applications (starter motors, electric drills) where efficiency is the sole selection factor.

Induction. An external field coil carries magnetic flux to a bi-metal armature. Eddy current in the armature induces a potent diamagnetic repulsion and ferromagnetic attraction. Repulsion/attraction results in the motor's considerable startup torque.

Compound. We have three windings, one is the field in the stator, a starting coil in the stator, and a third winding in the armature.

Rocmike in the last 23 hours under your Top Renner alias you have posted 4 hours. Under your Paul Wittenburg 3 hours. Under your Bill alias you have posted 7 hours and still posting. This is not counting your other aliases plus anonymous. Do you have any kind of life?

Tadpole, it is not necessary for anyone but leftists to resort to such cheap tactics as you use. Therefore your opinion is worthless, just like you.

Rocmike you need help. After over 5 hours of posting under Ladydarko, Lady Aban and Joyce Peller you posted for over 7 straight hours under your Bill alias. Bill finally stops posting and you immediately follow that with your Tweek alias with some anonymous posts thrown in. You have over 14 straight hours of posting. All repeating the same thing over and over and going to old questions and answers no one has been on in a long time. Rocmike take a walk if you are allowed, watch some TV, read a book, do some thing. This is not normal behavior.
