For more than 50 years, Wajax | Delom has offered extensive expertise in the repair, refurbishment and reliability of electric motors specific to steel mills such as DC split electric motors, armatures with equipotential connections, front-to-back armatures, synchronous electric motors and mechanical units such as gearboxes, fans and blowers. Wajax | Delom is a one-stop-shop for all rotating electromechanical equipment.

Thanks to our high capacity vacuum pressure impregnation (VPI) tank and epoxy varnishes, we manufacture and supply coils adapted to highly contaminated and high temperatures environments. We provide vacuum pressure impregnation for units of up to 16 ft. in diameter and all power.

We perform operational reliability audits, vibration analysis and predictive services to identify maintenance priorities and adapt repair and winding procedures to ensure that all units meet operational requirements.

Wajax | Delom also has a complete reverse engineering service for the custom manufacture of complete units or replacement components thus reducing replacement leadtime compared to a new unit or component. Every step of the manufacturing process (welding, machining, winding, etc.) takes place in our workshop, which allows for optimal control of costs and production leadtime.

Trust Wajax | Delom to protect your productivity.


Delom Services has grown with Quebec’s steel mills, and we have supported the industry through its best and worst years.

Over the past few decades, metal and steel markets have been more competitive than ever, with the arrival of new players.

The incentive to lower prices induces additional pressure on operations to do produce more, faster and at cheaper costs. As a result, production lines are pushed to their limits; they surpass their initially projected capacity and must do so with minimal unplanned downtimes.

Many electric motors used in the design of steel mills are no longer available, and equivalent alternatives, when available, vary in size and dimension, which greatly increases the vulnerability of the production line.

In this context, reliability is crucial, and Wajax | Delom is a partner of choice.
