Motor starting behaviour

Explain inrush and starting current and their effect on system voltage.

Predicting before you experiment is what makes the result stick. There is no penalty for being wrong here.

Start a motor across the line and then with reduced-voltage starting.

1. Start across the line and record peak starting current and the voltage dip.
2. Switch to a reduced-voltage or soft-start method.
3. Compare starting current, dip, and available starting torque.

Describe a load in your experience where the voltage dip on starting would be a problem.
