Ranking Criteria

1. The motor with a smaller output power gets a higher ranking than a motor with a larger output power. Motors with a smaller power are usually physically smaller and cheaper, and if a smaller motor can do the job it deserves preference. The power used to determine the ranking is the maximum output power P_max and it is determined by the formula ¹/₄T_stallω₀.
2. When two motors share the same P_max the efficiency of the total motor configuration determines the ranking. A more (energeticly) efficient configuration will get a higher ranking than a less efficient configuration.
3. If the efficiency of two equally suitable motors is the same the relative motorload is used. A higher loaded motor will get a higher ranking than a less loaded motor.

If there are more workpoints given by the user the average value for the efficiency and the relative motorload is determined and used.
