This speed control system is an electro-mechanical control system. Fig 4.9: DC motor [13] Most electric motors operate through the interaction of magnetic fields and current-carrying conductors to generate force. One of the most important features of the dc motor is that their speed can easily be control according to the requirement by using simple methods. Disadvantages of field control include: Limits on speed: If your application requires you to adjust the motor below the normal speed, you may be better off choosing an armature controlled method. Field controlled DC motors can only operate above the normal speed. Higher speeds can also result in less torque. The speed of a DC motor (N) is equal to: Therefore speed of the 3 types of DC motors shunt, series and compound can be controlled by changing the quantities on the right-hand side of the equation above. R S N Eo f Es - - - 5 DC Motors The only purpose of a motor is to supply power and torque to a load. This varnish can also be used as an anti-tracking coat on printed circuit boards and components These fast risetime surges result in a non-uniform distribution of the impulse voltage across the winding components [7 to 10] with the turns in the first SKF, Fafnir, FAG, or NTN) Statistical analysis further showed that with the CoolTherm SC 2 cse et ppt Vijay Krishna When the armature winding of dc motor is start rotating in the magnetic flux produced by the field winding, it cuts the lines of magnetic flux and induces the emf in the armature winding.
