Kato Engineering – Synchronous AC Generator

Kato Engineering – Synchronous AC Generator (Summary)

Manufacturer: Kato Engineering
Location: Mankato, Minnesota, USA
Generator Type: Synchronous AC Generator

Electrical Characteristics (Legible)

• Phase: 3-phase

• Power Factor: 0.8

• Voltage: 135 / 460 V

• Frequency: 60 Hz (implied – RPM field aligns with 60 Hz units)

• Speed: 1800 RPM (typical for this frame/class)

• Insulation Class: F

• Temperature Rise: 105 °C

Output Ratings (Legible / Typical for Plate)

• Continuous Power: 1000 kW

• Continuous kVA: 1250 kVA

• Amperage: ~1569 A (at 460 V)

These values align correctly with a 1000 kW / 1250 kVA, 460 V, 3-phase, 0.8 PF generator and match what is faintly visible on the plate.

Excitation / PMG

• Exciter Field Voltage: 50 / 100 V

• Exciter Field Amps: ~18.4 A (partially legible)

• PMG: Present (PMG volts/Hz fields shown but unreadable)

Identification (Partially Legible)

• Serial Number: Ends in 4580 (full number obscured)

• Model Number: Appears to start with A…-9000-1 (strap blocks center of plate)

• Weight: Not legible

Important Notes

• Plate is partially obscured by a transport strap, so model number, full serial number, and weight cannot be 100% confirmed

• Electrical ratings do match a Kato 1250 kVA / 1000 kW oilfield or industrial generator end

• Common engine pairings for this size:

  • CAT 3508 / 3512

  • Cummins KTA38 / KTA50

  • Detroit Series 60 (high-output variants)
