The StromerPower 90kVA Three Phase Alternator (STRO-88K) is a commercial-grade, three-phase low-voltage AC alternator engineered within a strict ISO 9001 quality assurance environment to deliver uncompromising reliability. Designed as a premium component for stationary diesel generator sets, mobile power plants, and industrial equipment, this 4-pole brushless alternator features high efficiency, low reactances, and exceptional motor-starting capacity under heavy starting loads.

  • Dual-Rating Performance: Delivers 80kVA Prime power and up to 90kVA Standby power output at a stable 50Hz frequency (PF = 0.8).
  • Advanced Voltage Regulation: Features the industry-standard SX460 AVR model maintaining a tight +/- 1% voltage regulation to shield sensitive equipment from fluctuations.
  • Clean Power Winding: Implements a 2/3 pitch stator winding layout that cleanly suppresses lower-order harmonic distortion, keeping Total Harmonic Distortion (THD) under 5%.
  • Rugged Mechanical Interface: Built with a resilient single-bearing configuration optimised for native SAE housing flange and clutch flex plate alignment setups.
  • Industrial Grade Protection: Outfitted with an IP23 weather-protective enclosure, Class H insulation, robust steel base, and dynamically balanced rotors compliant with ISO 1940 vibration specifications.
SUPERIOR QUALITY AND PERFORMANCE

Our company sets new global standards in quality in all the aspects from design, manufacturing, material selection, production and testing equipment, tooling, and quality control.

GENERAL SPECIFICATIONS

StomerPower 90kVA Alternator

Reinforce your facility's operational infrastructure and manage substantial commercial loads with the heavy-duty capacity of the StromerPower 90kVA Three Phase Alternator (Model: STRO-88K). Built intentionally to withstand the punishing strain of continuous backup cycles and high inductive spikes, this brushless synchronous machine serves as an excellent power core for substantial fabrication hubs, municipal installations, and busy retail parks. Operating at a steady 1500rpm, its self-excited 4-pole design provides superior internal thermal management, stopping premature insulation failure under heavy operational demand.

Engineered to distribute alternating current flawlessly across all three supply lines, the STRO-88K handles a sustained 81.8kVA prime load comfortably. Sourcing this genuine industrial-grade platform ensures that your primary manufacturing lines, ducted ventilation networks, corporate data clusters, and automated sorting centres stay completely active whenever the primary electrical grid collapses.

Advanced Multi-Phase Voltage Regulation and Harmonic Control Networks

Engineered with high-velocity internal cooling pathways and strict manufacturing tolerances, this unit integrates smoothly into custom containerised generator assemblies without creating excessive vibration transfer or mechanical crankshaft strain. The heavy steel framework and premium insulated copper stator layout provide engineering contractors with a long-term, dependable generation asset designed to perform in challenging operational environments.

StromerPower 90kVA Alternator Key Features

  • Substantial Phase Management: Delivering a continuous 80kVA prime capacity, this alternator reliably balances phase loads across multi-tenant commercial centers.
  • Low Vibrational Signature: Dynamically balanced internal components keep running harmonic resonance to a minimum, preserving bearing life inside enclosed custom canopies.
  • Optimised Coaxial Conversion: Crafted using high-purity copper windings that restrict internal impedance losses, directly supporting reduced fuel consumption on your diesel engine.
  • Rigid Base Layout: Built with a heavy-gauge steel frame to withstand structural twisting during tough site deliveries and high-torque start-up sequences.
  • Integrated Line Balancing: Factory-equipped with a precise Automatic Voltage Regulator (AVR) to counter voltage fluctuations instantly and protect sensitive digital logic boards.
  • High Thermal Protection: Uses premium H-class insulation material combined with an IP23 weather-protective shell to secure the internal windings in dusty or humid locations.
  • Expanded Junction Hub: A spacious top-mounted terminal enclosure gives maintenance electricians clear access for quick input wiring, diagnostics, and regulator fine-tuning.
  • Clean Waveform Delivery: Backed by StromerPower's established industry engineering, this low-reactance design limits wave distortion to maintain an exceptionally clean power wave.
