The AC Stator team provides the expertise required to rewind any stator; repair and recondition core laminations, insulations, housings, liners, flanges, terminals and lead wires; as well as install and repair terminal blocks and current transformers.

Highly trained repair technicians disassemble, reinsulate, rewind and repair main rotor assemblies; recondition laminations, insulations, windings and lead wires; repair loose cores, damaged shafts, bands, carriers, diodes and various hardware; perform complex assembly procedures; balance and overspeed as required.

This department can decipher the most challenging wiring schemes and rewind units using gauge sizes of 12 to 38, including: exciter stators, exciter rotors, PMG’s, roundwire armatures, stitch-wound stators, and other various units.

With many years of collective experience, these technicians have developed creative strategies and techniques to rewind and recondition series, interpole, compensation windings and insulations; shim poleshoes; repair leads, main and brush terminals (crown repair), end bell assemblies, housings, and terminal blocks.

From disassembling; re-insulating; installing coils, commutators and rings; to brazing, dipping, undercutting and balancing, our dynamic team of armature repair technicians yields an incredible output of armatures a month.

Equipped with the latest instrumentation, tools and sophisticated test equipment, our Q.C./Q.A. department is capable of accurately sampling, inspecting, and testing components to assure that they conform to OEM—defined specifications.

Engineering

Our qualified engineers are capable of reverse engineering nearly any generator sub- component. Using sophisticated CAD software, rewind/repair manuals are created, which are then approved by a Transport Canada delegated engineer (D.A.R.). Upon approval, all components are listed in our capabilities

Plating & Grinding

WAC’s highly skilled and fully certified technicians are capable of performing Nickel, Cadmium and Copper plating processes in accordance with AMS 2451, MIL-STD-865C and MIL-STD-2197. Through the use of computer—driven controllers, our technicians can perform grinding operations within ten thousands of an inch tolerance.

Machining

Through the use of both modern machinery and state of the art computerized automation, our highly skilled technicians can provide a range of precision machining functions including: cutting, milling, boring, tapping, turning and grinding.

Brazing

We have developed a new, custom—made brazing machine, which can accommodate a range of brazing and soldering applications. It’s highly efficient design produces reliable, smooth and uniform joints.

Balancing & Overspeeding

In addition to our Dynamics Research DSP-100 balancing machine, our newly acquired Schenck-Trebel HM2BK machine has doubled our output of precision—balanced rotable components. Our overspeed capabilities have been recently increased to achieve speeds of up to 45 000 RPM.

Welding

Our square wave AC/DC TIG (GTAW) welding machine has built in Auto Balance circuitry, which automatically provides the proper amount of cleaning and penetration when welding. Fully programmable welding presets allow our certified operators full control over any welding process, in full compliance with AMS-STD-2219.

Coil Manufacturing

Through comprehensive research and development, our engineering team has designed a computer—driven pneumatic coil manufacturing line, which provides a range of process functions including wire feeding, spreading, shaping, cutting, stripping and winding.

R&D

Our federal SR & ED—government funded Research & Development department presses forward with the latest advances in industry-specific technologies, with the aim of improving existing processes and advancing knowledge within the aircraft industry.
