WebMotor inrush current is different from transformer inrush current. Motor inrush current is due to the lack of back EMF limiting the current. Once the magnetic field is established in the coils a back EMF is generated. The waveform is usually sinusoidal with rounded peaks. The high current also occurs on both sides of the waveform. Web25 feb. 2024 · The induction motor draws a high starting current as compared to the running condition. The starting current of the induction motor is about 5 or 6 times the motor full load current. An induction motor of rating 11 KW,22 Amps,440 volts takes a high starting current of about 132 Amps. lockwood short backset mortice lock 3580 https://selbornewoodcraft.com
