The StromerPower 56kVA Three Phase Alternator (STRO-55K) 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 reactance, and exceptional motor-starting capacity under heavy starting loads.

  • Dual-Rating Performance: Delivers 50.9kVA Prime power and up to 56kVA 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 56kVA Alternator

Empower your intermediate industrial installations and commercial supply hubs with the supreme capacity of the StromerPower 56kVA Three Phase Alternator (Model: STRO-55K). Specifically developed to serve as a high-capacity replacement core or the foundation of custom standby assemblies, this robust brushless powerhouse excels under continuous load-shedding fatigue. Operating at a disciplined 1500rpm, its 4-pole excitation path features a low-reactance profile that manages steep inductive current draws comfortably, minimising heat accumulation within the stator housing.

Engineered to sustain a completely balanced multi-phase output, the STRO-55K provides a dependable 50.9kVA prime power rating. Fitting this genuine industrial-tier component to your power plant guarantees that large automated printing presses, central air handling networks, regional cold storage links, and computerised processing facilities run without interruption when grid infrastructure falters.

Comprehensive Multi-Phase Output Stability and Waveform Harmonisation

Featuring a highly efficient internal cooling fan system and dynamic rotor balance, this alternator reduces torsional strain on mating engine crankshafts, preventing structural alignment faults. The thick-gauge steel chassis and high-purity copper-winding layouts provide engineering firms and plant asset managers with an incredibly resilient long-term asset designed for continuous productivity.

StromerPower 56kVA Alternator Key Features

  • Substantial Load Equilibrium: Supplying a sustained 50.9kVA prime rating, this unit maintains excellent voltage balance across all three phases under uneven commercial building loads.
  • Acoustically Refined Profile: Tight manufacturing tolerances and strict vibration management limit internal operational resonance, aiding quiet canopy deployment.
  • Excellent Thermal Economy: Crafted with premium-grade insulated copper windings that reduce internal resistance, lowering overall engine fuel consumption during peak operations.
  • Structural Rigid Shell: The robust steel mounting base frame easily resists physical deformation during tough transport logistics or high-torque starting sequences.
  • Dynamic AVR Regulation: Arrives factory-equipped with a precise Automatic Voltage Regulator (AVR) module to suppress sudden line drops and protect sensitive electronics from voltage sag.
  • High-Tier Ingress Shielding: Utilises H-class thermal protective barriers combined with an IP23 enclosure to guard vital copper elements against high ambient heat and dust.
  • Technician-Friendly Layout: An expanded, easily accessible top terminal box simplifies phase configuration changes, primary connections, and AVR routine servicing.
  • Harmonic Distortion Guard: Backed by StromerPower's proven design background, the low-reactance assembly limits distortion to ensure a smooth, pure sine wave delivery.
