Example Regen Resistor Power Dissipation Calculation, continued

Example Step 2 Identify each deceleration of the plot where the drive is decelerating the load.

Example Step 3 Calculate the energy returned to the drive in each deceleration as follows:

Deceleration 1

ω = 2 π 3000RPM / 60 = 314 radians/sec

E = ½ 0.01kgm

(314 radians/sec)

= 493 joules

Deceleration 2

ω = 2 π 600RPM / 60 = 63 radians/sec

E = ½ 0.01kgm

(63 radians/sec)

= 20 joules

Deceleration 3

ω = 2 π 3450RPM / 60 = 361 radians/sec

E = ½ 0.01kgm

(361 radians/sec)

= 652 joules
