Switchgear. Controls. Motors. Generators.

Staffed with professionals that have an extensive knowledge of electric motor repair from fractional to multi-thousand horsepower, the Timken Power Systems (TPS) family of electrical brands form a coast-to-coast network designed to cover every aspect of marine electrical needs.

Our brands include H&N Electric, Smith Services, Maine Industrial Repair, and Schulz Electric, and represent centuries of combined hands-on experience: from equipment maintenance and repair, to engineering, to design and manufacture, to material management.

Switchgear. Controls. Motors. Generators.

Inspect. Repair. Upgrade.

It is often more economical to repair or rewind than replace motors and generators. Our team will inspect and advise as to what is the most cost effective option. All coils are inspected for fit, finish, electrical soundness and dielectric integrity, as well as being Hi-Pot tested to ensure insulationvalues, and surge tested at 100% of the original test voltage.

Windings that undergo vacuum pressure impregnation (VPI) are virtually impervious to oil, moisture and chemical contaminates. The VPI system results in the greatest mechanical strength for windings, a cooler running motor, improves performance and extends machine life. At up to 12’ in diameter, the TPS network has some of the largest VPI tanks in the country.

All of this investment in technology, machinery, SOPs, and manpower are in place to achieve one goal: to provide our customers with the assurance that their equipment is returned to them in “as new” condition, and with the peace of mind that our work is backed by the Timken Power Systems one-year warranty.

Finally, TPS sites incorporate a wide variety of testing programs to ensure that our customers’ motors or generators meet or exceed their performance expectations. Additionally, our brands have all been independently ISO 9001 certified, are registered with Underwriter Laboratories (508A UL), and are members of the Electrical Apparatus Service Association (EASA).

Decontamination Services

As part of the Timken Power Systems network, Philadelphia Gear – through its sister brand Schulz Electric – now has the ability to service equipment that’s been contaminated during the power generation process on nuclear vessels.

Though this is a relatively small part of the Navy’s fleet – there are eight motors on each CVN that fall into this category, for example – it does present a unique set of problems in the handling, decontamination and repair of critical equipment.

We have a solution. Schulz Electric is NRC licensed to decontaminate not only motors, but gearboxes and other mechanical or electrical parts as necessary, and return them to an unconditional free-release status.

Along with Schulz’s radiation safety officer, trained radiation workers receive and conduct surveys on incoming items to determine their level of contamination, which takes place in our 2,000 sq. ft. restricted access area.

Since securing our license and opening the facility in 2006, we have worked on more than 500 pieces of equipment, and are extremely proud of the fact that we’ve managed to return over 90% of those units to an unconditional free-release status.

All inspection, decontamination and repair work is conducted in compliance with 10 CFR 50 Appendix B, NQA-1-1994 Nuclear QA program, and ISO 9001-2008.
