Calculation example

The known values are:

  • Average braking power: 11.8 W
  • Deceleration ramp: 0.92 s
  • 6 brake applications per hour

Calculating the energy from the power of the deceleration ramp:

The specified deceleration ramp in seconds refers to a speed change of 3000 min−1.

Calculation of the deceleration ramp for MOVIMOT® performance drive unit:

For the deceleration ramp of 1.45 s, you can use deceleration ramp [3] (0.2 s) in the diagram.

Use the characteristic curve with the shorter deceleration ramp because a shorter deceleration ramp means more braking energy.

The diagram permits 310 J of braking energy for the 0.2 s deceleration ramp at 6 cycles per hour. In this case, the required 10.9 J can be dissipated via BW1.
