Method and apparatus for electrical dynamic braking

摘要: A dynamic braking circuit for use with bi-directional conveyor systems and other equipment having a soft start/hard stop capability in both directions of movement. The electrically brakes the rotation DC motor by short-circuiting armature motor, thereby creating reverse current magnetic field to oppose motor's rotation. uses high-voltage, high-current SCR's switch running (in directions) brake as quickly is possible that such current. operates without any in-series resistors or "smoothing" inductors which lower magnitude are gated "on" pairs per each half-cycle AC power supply, enhances noise immunity overall SCR control circuit.
