3 phase induction motor

A 3 phase, 8 pole alternator is star-connected. The stator has 160 slots with 6 conductors per slot with full- pitched distributed winding. If the rotor speed is 750rpm, estimate the Flux required in the air gap to generate an emf of 1000V between lines. Assume a distribution factor of 0.85.
