Figure 2.2 Natural braking curve for a 90 kW fan braking load power and torque as a function of speed. A natural braking curve can easily be drawn based on the power and speed at the nominal point applying the formulas (2.5) and (2.6). Natural braking curve with quadratic load — Figure 2.3 Cumulative braking time for, eg, a 90 kW fan. Braking ...

Conveyor Brakes
When specifying a conveyor brake, first determine how the brake is going to be used. Is the brake going to be used to stop the conveyor regularly or will it normally be used for holding (perhaps with an occasional an e-stop condition)? Some conveyors are designed to be completely dependent on the brake to stop the bel…
