Braking torques
An application brake with several braking torques is available for every motor frame size for an
optimum adjustment of the brake motor to the application. Starting from a standard braking
torque, the braking torques can be adjusted up or down.
When the braking torque is reduced, great wear reserves can be attained. A higher braking
torque is to be provided for lifting applications. In this case, the earth’s gravity acts as an
additional acceleration in a negative direction.
In addition, some applications require a 2-fold safety factor for the braking torque.
