The invention provides a permanent magnet invisible magnetic pole and salient pole electromagnetic composite excitation generator, and belongs to the technical field of automobile motor electric appliances. The generator is composed of an electronic voltage-stabilizing controller, a front end cover, a rear end cover, a hybrid excitation rotor and a stator. Rectangular permanent magnet steel is installed in rectangular grooves of rotor core salient poles, electric excitation windings are wound on T-shaped salient poles, magnetic fields in generator air gaps are commonly provided by the permanent magnet steel and the electric excitation windings, the generated magnetic fields right face the air gaps, magnetic leakage is little, through adjusting the size and the direction of energization currents of the electric excitation windings, the magnetic fields formed by synthesizing permanent magnetic fields with electric magnetic fields can be adjusted, voltages output by the generator is stable, and the safety and the reliability of automobile electric appliance equipment are guaranteed.
