FREQUENTLY ASKED QUESTIONS

What power capacities does the StromerPower alternator range cover?

StromerPower manufactures a comprehensive catalog of industrial, low-voltage AC alternators spanning from 12 kVA up to 1100 kVA. This extensive selection includes specialized high-performance single-phase models (such as the standard 13.5 kVA and 20 kVA units) alongside heavy-duty three-phase industrial configurations, matching perfectly with leading global engine setups.

What is a 2/3 pitch stator winding, and why does StromerPower use it?

The stator incorporates a sophisticated 2/3 pitch winding design to act as an internal electrical filter. Traditional full-pitch windings can generate lower-order harmonic voltage waves that distort power quality. StromerPower's 2/3 design actively suppresses these damaging harmonic anomalies, keeping Total Harmonic Distortion (THD) safely under 5%. This delivers clean sine-wave electricity, eliminates excessive heat buildup within the copper coils, and shields sensitive electronic equipment on your grid from clean-power faults.

What type of automatic voltage regulation (AVR) do these alternators use?

StromerPower alternators utilize premium industry-standard voltage regulators (including models like the high-precision SX460). These automated modules continuously monitor the alternator's electrical output loop to deliver an exceptionally tight ±1% voltage regulation window. This immediate, dynamic response counteracts sudden load steps, smoothing out line voltage dips or surges when heavy industrial machinery clicks online.

How are StromerPower alternators protected against harsh South African environments?

Every component is built tough to survive punishing field deployment:

  • Class M Insulation: Premium enamelled and epoxied cores, wires and insulation barriers withstand high operating temperatures and harsh environments without structural degradation.

  • IP23 Weather Enclosure: Provides reliable protection against light spraying water and keeps debris or fingers away from internal spinning assemblies.

  • Vacuum-Dipping Paint Treatment: A comprehensive vacuum pressure impregnation (VPI) process seals the copper coils with advanced varnish, delivering high-strength resistance against high-ambient moisture and airborne dust.

How do StromerPower rotors cope with continuous engine vibration?

Continuous torsional vibration from heavy industrial diesel engines can easily cause standard shaft assemblies to drift out of alignment over time. StromerPower eliminates this failure point by utilizing long-term sealed bearings and dynamically balancing every rotor in strict accordance with ISO 1940 standards. This high-integrity balancing limits structural bearing wear, mitigates harmonic rattle, and extends the mechanical lifecycle of the powertrain assembly.
