Motor selection
Based on the above calculation results, select the motor capacity by using the following formulae.
Select the larger of the two calculated values as the motor capacity. Also, when selecting a motor
,
take into consideration the errors in calculation and modeling. Select a motor whose capacity is at
least approximately 20% larger.
