WebElectromotive force (EMF) refers to the voltage generated by a spinning motor. Measuring this voltage in order to determine the rotational speed of a motor is commonly called Back-EMF since the voltage tends to "push-back" against the circuit driving current into a motor's windings. This speed indication may be used in motion control algorithms ... WebFrom eq. 1, emf generated per conductor = dΦ/dt = PΦN/60 (Volts) …..(eq. 2) Above equation-2 gives the emf generated in one conductor of the generator. The conductors are connected in series per parallel path, and the emf across the generator terminals is equal to the generated emf across any parallel path. Therefore, Eg = PΦNZ / 60A culligan water lubbock https://2brothers2chefs.com
