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.

    本发明涉及一种混合励磁液冷自励式电涡流缓速器,包括缓速器,缓速器包括左侧制动单元,左侧制动单元的左侧缓速器定子设置有若干个左侧定子磁极,左侧定子磁极右端为左侧定子磁靴,左侧制动单元与右侧制动单元对称设置,相邻的左侧定子磁靴上的磁极方向相反,左侧定子磁极的磁极与对称的右侧定子磁极方向相反;相邻两个左侧定子磁靴之间的空隙内固定缓速器左侧永磁体,左侧永磁体的磁极方向沿着周向设置,所述的缓速器转子上设置有发电机的转子,发电机的定子固定在左侧缓速器定子和右侧缓速器定子上,电涡流缓速器不工作时,磁场不通过缓速器转子,电涡流缓速器工作时,两侧磁靴和两侧的永磁体的磁场均通过缓速器转子,提高制动性能。
