Motor Alternator Set Repair Services

To rolling stock maintenance engineers HiTRANS™ offers the most cost effective solution to motor alternator (MA) set in-service failure.

Operative performing a motor alternator repair

 

Many of our customers were experiencing major issues with their motor alternators such as flashover. Motor alternator sets were being returned from other repairers and failing almost immediately in service. As a result, we were asked to develop a solution that ensured every motor alternator set we repaired would work under full load conditions first time, every time.

The result is HiTRANS™, our patented transient dynamic motor alternator set test process that electrically simulates full load conditions of any type. It replicates exactly what happens in service, which means that the unit has been tested at full working load before it leaves our facility.
Our repairs are proven to work first time, every time, and to a life expectation in line with the operating life of the train.

We believe that we are the first company in the world capable of simulating exactly the electrical load conditions both through the motor alternator set controller and the incoming electrification.

We know there are a range of issues that affect performance, such as carbon brush length, brush spring tensions etc which we work with customers methodically to eliminate modes of failure and improve performance of their MA sets. Fully load testing each component to prove performance prior to dispatch.
