H&N Electric™ serves wind turbine operators in the Western United States with comprehensive, ISO certified wind-generator repair services. While any shop can help reduce turbine downtime, H&N goes beyond with rapid parts availability and a patent-pending EnduraPlus® winding process to upgrade wind motors and generators beyond OEM spec.
Wind generator repair services
H&N is no stranger to wind turbine and generator repairs — whether due to damage incurred during normal operation, or because of quality oversights unfortunately common in today’s manufacturing.
Our three full service wind motor repair centers are more than equipped to diagnose, solve, and repair (or re-manufacture) every major large wind turbine component, including generator shafting, power slip rings, housings, and more.
As a distributor of a wide array of generator repair products — and thanks to our expanded facilities and deep wind expertise — we can perform exacting, permanent gouge and indentation repairs with as little as one day of curing time. Our goal: Minimize your downtime, prevent future damage, lower total operating costs, and keep your generators operating at peak performance.
Upgrade your machinery with the EnduraPlus® process by H&N
When industrial motors and generators fail, mass-produced stock rotor and stator components are often the cause. Stock insulation and machine winding, as well as parts optimized to reduce costs, can yield major inefficiencies — typically with higher stator conductive losses — eventually leading to overheating, damage, and failure.
H&N developed the proprietary EnduraPlus® process to drastically improve and outperform stock wind rotor and stator performance.
EnduraPlus is custom, per-unit process that addresses common points of failure in wind generators to prolong the lifespan and efficiency of your critical machinery.

EnduraPlus: Proven in the field by a leading wind generator operator
reduced conductor l2R losses at full generator stator load for increased efficiency, lower temps, longer lifespans and greater outputs
greater voltage withstand than standard “double-build” insulation, reducing inter-turn faults and extending machinery lifespan
extra reduction in eddy and circulating current losses with EnduraPlus 4-circuit delta connection winding technology for enhanced efficiency
reduction in stator losses (2.1 kW) for total efficiency compared to OEM design with comprehensive EnduraPlus upgrades

EnduraPlus is proprietary to H&N Electric (patent pending). All results represented are based on customer redesign findings for a 660 kW wind generator. Stator and rotor design and insulation specifications will vary for each specific machine and customer specifications. As a result, test results will vary and all information provided herein is as is, without warranty or liability. EnduraPlus is a registered trademark of the Timken Company or its affiliates.
