An alternator stator is the stationary laminated core of an alternator that carries the operating windings where electric current is generated. The stator consists of a ring core assembled from stamped silicon steel laminations with precision slots for copper windings. It serves three critical functions: generating AC power through electromagnetic induction, acting as a magnetic core to distribute magnetic flux, and dissipating heat from the windings .

Reenives manufactures high-quality alternator stator cores using non-grain oriented electrical steel with advanced epoxy powder coating — delivering low core loss, high magnetic flux density, and superior thermal management for both automotive and UAV power systems .

Reenives offers alternator stators in multiple configurations to meet diverse application requirements :

• By Slot Count: 36-slot (modern high-performance alternators), 18-slot (early automotive designs).
• By Slot Shape: Open slots (rectangular cross-section, requires winding fixation), semi-closed wedge-shaped slots, and semi-closed slots for single-coil windings .
• By Material Thickness: 0.20mm (high-frequency UAV applications), 0.35mm (standard automotive), 0.50mm (heavy-duty industrial generators).
• By Winding Layout: Loop distributed scheme, wave concentrated scheme, wave distributed scheme .
• By Insulation Coating: C5 epoxy powder coating (Class H, 180°C) with ≥1800V dielectric strength.

💡 Reenives specialty: private mould development for any custom alternator stator geometry — with progressive die stamping ensuring ±0.02mm tolerance and optimal slot fill.

All parameters validated by Reenives R&D center (ISO 9001:2025) and third-party testing per IEC 60404-2, ASTM A937. Critical for alternator stator selection in power generation applications .
