A self-charging type electromagnetic retarder including a main portion having a stator yoke, a plurality of magnetic coils forming multi-phase connections, and a steel rotor, a control device, an electromagnetic retarder having a high revolution region, capacitor portion for storing excess electric power, a diode, and a low revolution region. The magnetic coils of each phase are connected with capacitors to form a resonance circuit. Transistors for the high revolution region are connected in series to each of the multi-phase connections. Transistors for the low revolution region are connected in series to each of the multi-phase connections through the capacitor portion and the diode. At the high revolution region, excess electric power obtained from the electric power generating type electromagnetic retarder portion is stored in the capacitor portion, and at the low revolution region, the magnetic coils are excited by the electric power stored in the capacitor portion.
