Claims

[Scope of utility model registration request]

A DC machine for vehicles using field control, which has a starting resistor to limit the inrush current flowing into the armature circuit when starting the motor, and an absorbing resistor to absorb the regenerative current to prevent battery damage and characteristic deterioration during regenerative braking. In the regenerative braking device, a control resistor that shares at least a part of the starting resistor and absorption resistor, and a switching means that connects the control resistor to the starting side when the motor is started and to the regenerative braking side when regenerative braking is applied. and a control means for detecting the regenerative voltage of the DC machine during regenerative braking and controlling the regenerative current flowing through the control resistor in order to consume excess regenerative energy. Aircraft regenerative braking system.
