Define Motor Parameters

Step 1

Click  Define Motor Parameters to obtain an estimate of the motor circuit parameters using the name-plate values and the speed-torque curve of the motor. Notes provided in the upper left corner of this window are instructions on how to use this tool to derive the motor parameters.
