  Speed control of dc motor | PPT - SlideShare

  Jul 14, 2016 · 3. SPEED OF A DC MOTOR We know, back emf of a DC motor Eb is the induced emf due to rotation of the armature in magnetic field. Thus value of the Eb can be given by the EMF equation of a DC generator. Eb = PØNZ/60A where, P= no. of poles, Ø=flux/pole, N=speed in rpm, Z=no. of armature conductors, A=parallel paths
