- Hi Pot test
Derived from the traction motor specifications, Houghton International uses a route card system to record test data and track the status of every traction motor in our facility. Route cards include an initial test and data report, assembly data report and test sheet and are populated at each stage of the repair process which highlights any defects that are present.
Route cards have specific job numbers and are cross referenced with product serial numbers to identify each product. The commutator profiles are carried out on receipt of the product, through each stage of the repair and also during the final inspection.
