Permitted work
done by the brake
If you are using a brake motor, you have to check whether the brake is approved for use
with the required starting frequency Z. The following diagrams show the permitted work
done W
max
per cycle for different brakes and rated speeds. The values are given with
reference to the required starting frequency Z in cycles/hour (1/h).
Example: The rated speed is 1800 rpm and the brake BM 32 is used. At 200 cycles per
hour, the permitted work done per cycle is 9000 J (→ Figure 48).
