The a.c/d.c. generator - electromagnetic torque, Electrical Engineering

Note, the armature current is produced in pulses as the armature rotates under the poles, so the torque also pulsates.

This can give rise to extra wear on bearings and the engine providing the power to turn the generator and has led to a preference to use three phase designs that do not suffer from this problem
