Web2 days ago · The field winding in shunt DC motors is made of many windings of thin wire, to both increase the magnetic field’s strength and limit the current through the coil. By doing … Input Voltage provided to the motor armature performs the following two tasks: 1. Controls the induced Back E.M.F “Eb” of the Motor. 2. Provides supply to the Ohmic IaRadrop. i.e. V = Eb + IaRa….. (1) Where 1. Eb = Back E.M.F 2. IaRa = Armature Current X Armature Resistance The above relation is known as … See more Multiplying both sides of Voltage Equation (1) by Ia, we get the power equation of a DC motor as follow. VIa= EbIa + Ia2 Ra….. (2) Where, 1. VIa = Input … See more black and green dress shirt
