Abstract

In this paper, a vehicle stopping method using an electric brake until a traction motor is stopped is studied. At the moment of vehicle stop, electric brake is changed to control mode wherein torque is reduced at a low speed. Gradient is controlled by estimating the load torque of motor thereby traction motor is not rotated after stop. In addition, coasting operation and brake test were performed from normal-opposite operation and start using a small-scale model comprising the inertial load equipment and the power converter. Further, traction motor was made to be equipped with a suspension torque. Pure electric braking that makes traction motor stopped by an air brake at the time of stop was also implemented. Constant torque range and constant power range were expanded during braking so that braking force was secured with the electric brakes even in high speed region. Therefore, vehicle reduction effect could be expected by reducing parts related with an air brake which is not used frequently by using a pure electric brake in the M car in wide speed region. Further, maintenance of brake system could be reduced, Besides ride comfort of passenger in the electric rail car, energy efficiency improvement, and noise reduction effect could be additionally expected.
