Cabinet Cooling
Use the cabinet loss and power dissipation values in this section along with the formula in “Cabinet Cooling
Calculations” below to calculate cabinet cooling for each installation. Following are tables showing power
dissipation for various drive/controller and motor combinations.
IPA04-HC Model
Power Dissipation for IPA (400 Watt Model)
IPA15-HC Model
The following values have been measured using the Parker MPM1421CSJXXXN motor.
Power Dissipation for IPA Cabinet Cooling Calculations
Cabinet Cooling Calculations
Use the motor’s speed torque curve to determine the torque when the motor is at running speed for your
application. If the torque is not known, use the “knee” of the graphed motion (where the peak-torque curve
intersects the continuous-torque curve)—this assumes the worst-case scenario for continuous motion.
power dissipated to cabinet (Watts)
shaft power of the motor (Watts)
efficiency of motor, approximately 0.85
efficiency of drive, approximately 0.90
