Title:
Electronic circuits to ensure that motor-driven doors of railcars are closed
Document Type and Number:
Japanese Patent JP6297212
Kind Code:
B2
Abstract:
The disclosed embodiments relate to an electronic circuit for a motor-driven door of a rail vehicle, said electronic circuit having a series circuit of a first non-linear element and a first controllable switch between the motor terminals. The first non-linear element is poled such that the resistance thereof to a current generated by the drive motor during a closing movement of the door is greater than during an opening movement. If a supply voltage for the door is present, the resistance of the first switch is effected relative to the resistance when said supply voltage is absent. The invention further relates to a door module for a rail vehicle having such an electronic circuit, to a rail vehicle for such a door module, and to a use of the electronic circuit.
