Why are some motor part numbers 8 digit and some are very long and contain non-numerical characters?
The 8 digit part numbers are either stocked or standard non-stocked parts that have been set up at our factory. The part numbers that are not 8 digit are numbers that are built up to designate all motor characteristics needed to order the motor. These numbers are what we call Matrix numbers and they are built off a matrix (please click on matrix to go to the download page. There you can click on the link to motor file downloads).
