Electrical Power Generation & Start Solutions
The combination of the electrical starting and power generation functions in a single unit, leads to the best trade-off
between weight, size and power.
The extensive use of electrical power represents a significant step forward in the move towards more environmentally-friendly aircraft by decreasing CO2, NOx and noise emissions. It will significantly reduce the Direct Operation Costs.
The shipset of Thales electrical component draws on new
technologies and meets the energy requirements of a business aircraft with the highest levels of comfort and performance as well as the ability to start latest-generation engines
that consume less fuel and produce less pollution.
The shipset includes two starter-generators for the main
engines, one starter-generator for the auxiliary power unit,
three electronic regulators, one electronic starter converter
and three transformer rectifier units.
Key Features
Power
Up to 65 kVA
Rated voltage
115 or 230 Vac
Torque
Up to 150 N.m

MOTOR CONTROLLERS - START BOX UNIT
The Start Box Unit (SBU) is part of the Power Generation
and Conversion System from Thales. Main Customer benefits
are :
„„ Mastery of engine start control
„„ The only one converter needed to start sequentially
APU and engines
„„ Easy maintenance
„„ Accereleration and torque control
„„ Producer of platform overall Direct Maintenance Costs

AC STARTER-GENERATOR
Using state-of-the-art technology developed through years
of experience and continuous development, Thales is a major
player in designing high quality AC Starter-Generators for
all types of aircraft.
Primary AC Starter-Generator functions are:
„„ to electrically start engines
„„ to generate the main electrical power for the aircraft
network
AC Starter-Generator is a 3-stage, brushless, synchronous
machine. Main stage is made of salient or non salient
pole. Pilot exciter stage is made of one Permanent Magnet
Generator (PMG), one exciter connected to rotating diode
bridge. Associated to Start Box Unit, Thales AC Starter-Generators are optimized to supply maximum starting torque.
