Thales designs Direct Current Generators for the Aerospace
industry. Boosting the latest technological advances, these
generators offer continuous improvement of performances.
Thales high-reliability brushless design allows optimized scheduled maintenance, decreasing the Direct Maintenance Costs
(DMC).
Thales DC Generator is a 3-stage brushless machine. The
third stage is the electrical power source. It is energized by
a 6-pole rotor, delivering rectified DC voltage (via a rectifier
bridge) to the aircraft electrical network.

Power rating up to 15 kW
Nominal rotation speed up to 13,700 RPM
Self-cooled
Clockwise or counter clockwise rotation
Via an ARINC 429 line, the DGCU sends all electrical data
to the EICAS (Engine Indicating Crew-Alerting System) and
to the maintenance system.

Generator Control unit (GCU) and Digital Generator Control
Unit (DGCU) match the generator’s needs.
Under normal conditions the GCU closes its excitation relay
and the line contractor, so the DC power supplies the DC
bus bar.
The Digital Generator Control Unit (DGCU) maintains a
constant generation output voltage and provides equal
load distribution in a parallel generator system.
