DC Injection Brake

Dynamic, automatic A-Stop

Essential criterions when braking motor is to accomplish it controlled, safely and powerfully and A-Stop makes it possible!

A-Stop brakes definitely in spite of running speeds and loads. A-Stop brake fits to all kinds of squirrel-cage motors in situations where machine must stop controlled. A-Stop will not stress motor or hardware.

Operating principles of patented A-Stop brake.

After opening the start-up contactor the logic of the brake receives information to stop the motor and switches brake contactor and gives control to the thyristor. Motor brakes with torque set by motor and thyristor. Logic receives information of the motor speed in real time.

When the speed of the motor is zero logic switches off thyristor and opens the brake contactor. Motor is ready to use immediately. A-Stop brake works automatically and absolutely without adjustable or fixed brake time.
