Most motors connected directly to AC power are likely to be induction motors, which require no special magnets. From fans, to fridges, to AC etc. Because they don't need drive electronics they can be very cheap compared to BLDC and the like, which would need power conversion from AC. Turbine generators typically use Synchronous motors, which often use DC to generate the opposing magnetic field ("exciters"), though they can also use permanent magnets for the same effect.
