13.2 Integrated braking resistor BW1
The following diagram shows the load capacity per braking operation of the BW1 braking
resistor integrated in MOVIGEAR
®
as standard:
13.2.1 Calculation example
The known values are:
• Average braking power: 144 W
• Brake ramp: 2 s
• 200 brake applications per hour
Calculating the energy from the power of the brake ramp:
The brake ramp [3] (0.2 s) can be used for the brake ramp in the diagram. Use the
characteristic curve with the shorter brake ramp because a shorter brake ramp means
more power.
The diagram allows a power of 290 J with a 0.2 s brake ramp at 200 cycles per hour. In
this case, the required 288 J can be dissipated with BW1.
