Rewinding

Buna Electric has a climate-controlled winding facility, where we use high-quality materials and craftsmanship to deliver reliable winding and other industrial motor services. We can rewind fractional horsepower motors up to 6,000 hp. We also work on all types of pumps, stators, armatures, field poles, and interpoles. With our unmatched workmanship and class-F and class-H insulation materials – including inverter-duty magnet wire – Buna provides elite rewinding.

Our rewinding expertise includes :

  • Single-phase, three-phase, and multi-speed winding
  • Testing voltages, from 110 to 4,160
  • A/C, D/C, and synchronous motors
  • Fields, armatures, and interpoles
  • Specialty coils

Vacuum Pressure Impregnation

Buna has a vacuum pressure impregnation system manufactured by Epoxylite Corporation. It is specially designed to provide complete and void-free impregnation of dry wound-insulated form-wound stators to meet IEEE specifications for sealed systems.

We use Epoxylite 478 resin in place of conventional varnishes to create a completely filled 100% solid insulation structure. This special resin provides a smooth, continuous coating on external and internal surfaces of the wound coils. Also, the resin doesn’t flow from the slot area during the cure cycle.

Our impregnation system has the unique ability to produce random-wound stators capable of passing IEEE specifications of sealed systems. The system also does impregnation for other electrical apparatus such as field coils, armatures, stator, wound rotors, and transformers. Vacuum pressure impregnation is just one of the many industrial motor needs Buna provides.

Contact Buna for vacuum pressure impregnation.

  • High-current test to check broken rotor bars
  • A/C and D/C voltage drop test on fields and interpoles

Balance/Vibration Analysis

Balancing

Buna’s dynamic balancing extends the life of your equipment and reduces wear and tear on your rotating machinery. We handle all of your balancing needs up to 20,000 pounds and 7-foot swing. We balance most rotors in anti-friction bearing assemblies. For rotors with bearing already on a shaft, we use V-blocks and put the bearing on them. We use a mandrel for rotors and fans without shafts from both ends. Balancing is part of the comprehensive industrial motor services Buna provides.

We service most types of rotating apparatus related to motors including:

  • Fan blades
  • Motor rotors
  • Pump impellers
  • Other rotating equipment

Vibration Analysis

Excessive vibrations in rotating machinery can be very loud and, more importantly, substantially reduce the life of shaft bearings. Vibration analysis solves these problems.

Buna has on staff a certified vibration analyst, so we do on-site machinery vibration analysis with high quality control. Our capabilities are vast from a spot check on a machine to a complete vibration-analysis program for your machinery.

  • CSI 2130 vibration analyzers, on-site and in the field
  • Balance machines, up to 20,000 pounds and 7-foot swing
  • Field-service analyzing and reporting
  • Certified technicians
  • Installation and calibration of Bently Nevada displacement probes

Contact Buna for balancing and vibration analysis.
