Answer Posted / vijendra joglekar
There are two reasons
1.At starting the motor will behaves as low resistance circuit.
As we know the fundamental i mean when the
resistance is low the current will be high.
2. At starting the back emf will be zero
As we know the voltage equation of motor
V=Eb+Ia Ra
Where Eb is the back emf which is zero at starting
V is they supply voltage
Ra is they armature resistance which is very small
hence we can prove that by using the equation.
