A-Stop® - automatic and fully electric DC Injection Brake

 

A-Stop® DC Injection Brake enables:

  • dynamic and safe, but still powerful stopping of a motor, regardless of the running speed or masses.

  • fits for every kind of squirrel-cage motors and wide variety of power and voltage ranges.

  • inexpensive, simple and easy to install

  • a reliable option for example frequency transformer with a brake resistance.

 

DC Injection Brake basic models:

A-Stop® 400-500 Volts

A-Stop® 690 Volts

 

Principle

 

The logic controller switches on the brake contactor and gives the control to the thyristor. The motor brakes by the moment of the motor and the thyristor. Logic gets continuously information of the motor speed and when it reaches zero, the logic switches off the thyristor and opens the brake contactor. The motor is instantly ready for restart.
