Gearbox motors GFC Product Catalog 2012 / 149 9 Possible classification Brake torque values/motor: Brakes with various torque ratings can be attached to a motor of a given installation size. In a normal use case, it is recommended to select brakes with torque ratings which correspond to the 1.5 to 2-fold nominal motor torque. For actuators used in carriages, Integrated motor brake (single-surface brake.)

In such cases, please indicate to us the exact operating conditions – including the output torque of inertia – to enable us to calculate the permissible brake torque.
