As　one　of　the　most　common　auxiliary　braking　devices,　eddy　current　retarder　can　greatly　improve　the　safety　and　comfort　of　driving.　Eddy　current　retarder　is　extensively　applied　due　to　its　simple　control　and　low　cost.　This　paper　presents　a　novel　structure　of　eddy　current　retarder　in　which　the　coils　are　wound　at　the　bottom　between　the　salient　poles　of　the　stator　of　the　retarder.　Compared　with　traditional　hub-type　eddy　current　retarder,　coils　and　stator　salient　poles　have　higher　space　utilization.　The　novel　eddy　current　retarder　is　preliminarily　analyzed　based　on　the　electromagnetic　theory,　and　the　finite　element　method　is　used　to　analyze　the　performance　of　the　novel　eddy　current　retarder.　The　novel　eddy　current　retarder　with　the　same　design　space　and　weight　was　compared　with　the　traditional　hub-type　eddy　current　retarder.　According　to　the　analysis　results,　the　braking　torque　performance　of　the　novel　eddy　current　retarder　are　better　than　that　of　the　traditional　hub-type　eddy　current　retarder　at　the　low　speed　and　large　coil　current.　©　2021　IEEE.
