Brushless Alternator

Product Overview

HONOUR BYG Series Brushless Alternator for Industrial Facilities

The HONOUR BYG series brushless alternator is a heavy-duty AC synchronous alternator engineered for industrial enterprises and commercial businesses, delivering reliable power from 8.5–2500kVA. Equipped with an AVR excitation system, H-class insulation, and IP22/IP23 drip-proof construction, this alternator is built for continuous operation in power stations, manufacturing plants, and heavy industrial environments.

Unlike brushed units, it eliminates carbon brushes, reducing wear, sparks, and routine replacement. Combined with 100% copper winding and precision-machined rotor and stator, it meets strict demands for stability, efficiency, and low maintenance in industrial power generation.

Key Technical Advantages

High Power Output for Heavy Industrial Loads

The BYG series covers a wide power range of 8.5–2500kVA, suitable for large power stations, heavy production lines, and high-demand industrial sites. Optimized electromagnetic design ensures steady peak output, supporting sudden load changes during equipment start-up and continuous operation.

High Efficiency & Low Transmission Loss

Constructed with pure copper windings and optimized layout, the alternator minimizes AC power loss over long distances. When paired with transformers, it improves transmission efficiency and reduces operational costs for facilities with remote power distribution.

Stable Voltage & Frequency Regulation with AVR

The integrated AVR (Automatic Voltage Regulator) enables precise adjustment of voltage and frequency by controlling excitation current and rotor speed. Key performance metrics include:

Steady voltage regulation: 1%

Transient voltage: –15% to +20%

Voltage waveform distortion: ≤3%

Telephone harmonic factor: ≤50

This stability ensures clean power for sensitive and precision industrial equipment.

Brushless Design – Low Maintenance & High Reliability

Removal of carbon brushes eliminates common failure points and reduces maintenance frequency. The compact structure simplifies operation and inspection, requiring minimal manual intervention. In harsh industrial conditions, it delivers a long service life and reduces downtime.

H-Class Insulation & IP Protection for Harsh Environments

Insulation class: H (125℃–40℃) – excellent heat resistance and aging resistance for high-temperature workshops.

Protection class: IP22 / IP23 – drip-proof and dust-resistant, suitable for humid, dusty, and demanding industrial environments.
