Remember, always take the data from the motor recommendations and place it into your decision matrix. Many sites will provide their recommendations, but it is very unlikely that the motor supplier’s decision matrix matches your own. It is also unlikely that the manufacturer’s selection tools will consider parameters such as lead-time, design margin, or aesthetics. Your own selection criteria may change through the design process, so recording all of the motors’ parameters in your decision matrix is important. What may seem like a poor match initially could end up being the best option if one parameter’s weighting is changed.

It is recommended to alter your input values to the selection tool to determine the sensitivity to your calculated inputs. For example, if the operating torque is 1 Nm instead of 0.865 Nm, how does this alter the tool’s recommendations? For any values that may have some uncertainty, it is a good idea to change input values. Key values that should be altered are the operating point and the power supply.
