The invention relates to a hybrid excitation liquid cooling self-excitation type eddy current retarder which comprises a retarder. The retarder comprises a left side braking unit, a left side retarder stator of the left side braking unit is provided with a plurality of left side stator magnetic poles, the right ends of the left side stator magnetic poles are left side stator magnetic shoes, and the left side braking unit and a right side braking unit are symmetrically arranged. The directions of the magnetic poles on the adjacent left stator magnetic shoes are opposite, and the directions of the left stator magnetic poles are opposite to the directions of the symmetrical right stator magnetic poles; a retarder left side permanent magnet is fixed in a gap between every two adjacent left side stator magnetic shoes, the magnetic pole directions of the left side permanent magnets are arranged in the circumferential direction, a generator rotor is arranged on the retarder rotor, a generator stator is fixed on the left side retarder stator and the right side retarder stator, and when the eddy current retarder does not work, the magnetic field does not pass through theretarder rotor; when the eddy current retarder works, the magnetic fields of the magnetic shoes on the two sides and the permanent magnets on the two sides all pass through the retarder rotor, and the braking performance is improved.
