Why Doesn the Starter Motor Turn the Opposite Direction When Polarity is Reversed?
Technical information submitted by David Dare (Ebay ID: simplyconnected ) Direct Current Motors have two basic components, the stationary Field poles (which produce magnetism) and the rotating Armature (which also produces magnetism). The Armature uses brushes so it can always be in the optimum position for the strongest magnetic pull, causing the motor shaft to turn. Armatures and Fields are wired in one of three ways, and I am DEFERRING permanent magnet field motors until later. These are all used for different applications. Series Field: This wiring method produces the STRONGEST starting torque, but poor speed regulation. The armature is wired in series with the field wires, which means the field wires have to carry the same current as the armature (VERY heavy field wires, lots of current makes lots of magnetism, creating lots of torque). Shunt Field: The armature is wired in parallel with the field. Very small field wires (and many more turns), great for speed regulation, but poor
