Determine the suitable lapping on an auto-transformer starter for an induction motor required to start the motor with 40 per cent of full-load torque. The short-circuit current of the motor is 5 times the full load current and full-land slip is 0.035. Also deternmine the current drawn from the mains as a fraction of full-load current.
