34 Magnetic lines of force from the interpoles are cut, creating a canceling voltage that neutralizes the unwanted voltage (that is produced by distorted lines of force). Electric Motor Maintenance and Troubleshooting generating a voltage in them. This voltage is the opposite polarity of the unwanted voltage described above and cancels it. The result is less arcing. The polarhy of the interpoles is very important. If the polarhy is wrong, the voltage generated b}' them will add to the unwanted voltage instead of canceling it.
14 illustrates what happens to some of the lines of force when oversaturation occurs. 13 A stator (with an is aligned, there is no electromagnet in its torque, and it becomes bore) illustrates basic part of the magnetic motor action found in path. all motors. 14 Oversaturation causes magnetic lines of force to go through the air (when there isn't room for them in the iron). Magnetic Balance When electric motors and generators are designed, great care is taken to magnetically balance all the poles.
Torque of the DC Motor The DC motor has very good torque characteristics. The commutator switches one circuit at a time in the armature slots. The slots contain one or more coils (circuits). As these coils are commutated, they control the magnetizing of the slot's iron teeth. As the magnetism in the iron of the armature changes from north to south, it does so one tooth at a time, resulting in a very smooth torque at all speeds. The Shunt Motor The shunt motor has two circuits: the armature and interpoles (A1 and A2) and the shunt field (F1 and F2) (Fig.
