Recent Project: Comprehensive Overhaul of AC Brushless Generator

We're proud to announce the successful completion of a scheduled 50,000-hour overhaul on an 810 KW Kato DP Synchronous AC Brushless Generator. This meticulous process involved a series of intricate steps to ensure optimal performance and longevity:

1. Initial Assessment: Conducted thorough visual inspections and operational tests, followed by careful dismantling.
2. Component Refurbishment: Employed proven cleaning methods to preserve the integrity of all parts, focusing on the rotor and stator's condition, and meticulously steam cleaned and oven-dried components.
3. Advanced Testing & Treatment: Executed a series of electrical tests (IR, winding resistance, polarization index, surge comparison), alongside mechanical inspections of critical parts. All windings received a varnish treatment and oven cure for enhanced protection.
4. Precision Balancing & Final Assembly: Achieved dynamic balance for all rotating components to ISO G1 specifications, followed by reassembly, hardware torque application, and comprehensive sealing and painting for lasting durability.

Understanding Brushless Generators: A Blend of Innovation and Efficiency

Brushless generators stand at the forefront of electrical generation technology, merging reliability with efficiency. These generators capitalize on electromagnetic induction, a principle championed by Faraday, to transform mechanical energy into electrical power without the drawbacks of brush wear and maintenance.

• Core Components:
• STATOR: The static powerhouse with embedded windings.
• ROTOR/ARMATURE: The dynamic heart, spinning within the magnetic field to generate electricity.
• RECTIFIER: The bridge converting AC to DC, ensuring a steady power output.
• Advantages:
• Enhanced lifespan and reduced maintenance, thanks to the absence of brushes.
• Higher efficiency and operational cost savings.
• Challenges:
• Initial cost and complexity, requiring specialized knowledge for repairs.
