Example Regen Resistor Power Dissipation Calculation

Example Motor The following is an example application of each step in the power dissipation

and Drivecalculation procedure using the motor, drive and input power specifications

Specifications identified below. Refer to the power dissipation calculation procedure presented earlier in this chapter.

λMotor = BPH1423N with brake

Total Inertia (JT) = JM + JB + JL = 0.002 + 0.001 + 0.007 = 0.01 kgm2

where:

Motor inertia (JM) = 0.002 kg(m2)

Brake inertia (JB) = 0.001 kg(m2)

Load inertia (JL) = 0.007 kg(m2)

λDrive = MHDS1028N00

λLine Voltage = 480 Vac
