Electromagnetic retarder capable of energy recovery

The invention discloses an electromagnetic retarder capable of energy recovery. The electromagnetic retarder comprises a stator, a rotor, a power electronic module and a transmission shaft, wherein the power electronic module is connected with the rotor via a reversing valve. The retarder is characterized in that the stator is arranged in the stator, and a gap exists between the rotor and the stator; the stator comprises a stator support, a generating armature, a liquid cooling isolation module and a cylinder which bears eddy current, and the stator support is connected with the transmission shaft via a bearing; the liquid cooling isolation module is arranged between the generating armature and the cylinder; the generating armature comprises a generating armature winding and a generating armature iron core, is connected with the stator support; and the rotor comprises a rotor support, an excitation winding and an excitation iron core, and the rotor support is connected with the transmission shaft, and the excitation winding. The electromagnetic retarder capable of energy recovery is simple in structure, small in size and high in braking capability.
