Abstract
PURPOSE: To prevent a rapid change of a braking force at a change over of resistors by detecting that a vehicle speed reaches to a predetermined value with a vehicle speed detector, and then decreasing a field current to a predetermined value to change over a resistor in a dynamic brake at braking.
CONSTITUTION: When a main motor 8 is operated as a separately excited generator by connecting its armature to a dynamic brake resistor 11 and closing a braking switch 15 to decrease a current of a field winding 13 through a rectifier 4d at dynamic braking, a decision circuit checks whether a vehicle speed reaches to the speed to be change over reistance of the dynamic brake resistor 11 or not base on an output from a vehicle speed detector and commands to decrease the field current to a predetermined value and the resistor is changed over with a circuit breadker 12 after detection of this decrese. By this means, a smooth change over of the brake resistor can be made without a rapid change of a braking force in a main circuit.
