Example Regen Resistor Power Dissipation Calculation

Example Motor
and Drive
Specifications

The following is an example application of each step in the power dissipation
calculation procedure using the motor, drive and input power specifications
identified below. Refer to the power dissipation calculation procedure presented
earlier in this chapter.
