Alternator Parts for Generator Sets
The alternator (generator end) converts mechanical energy from the engine into electrical energy. We supply alternator parts for Stamford, Leroy Somer, Marathon, and Mecc Alte.
Key Alternator Components
- Rotor — Rotating part generating the magnetic field
- Stator — Stationary copper windings where current is induced
- Bearings — Support smooth rotation; worn bearings cause noise and vibration
- Voltage Regulator (AVR) — Maintains stable output voltage
- Stamford: SX460, MX341, MX321, AS440
- Leroy Somer: R438, R448, R450
- Marathon: MC series, MAX series
- Carbon Brushes & Brush Holders — Transfer current to rotor; periodic replacement needed
- Rotating Diode Assemblies — Convert AC to DC for field excitation
- Rectifier Plates — Essential for proper voltage output
- Coupling Discs — Connect alternator to engine
- Cooling Fan — Prevents overheating during operation
- Surge Suppressors — Protect against voltage spikes
- Insulation System — Protects windings from heat and moisture
