IL REGOLAMENTO
Extract from 2009 F1 technical regulations:
…“1.20 Kinetic Energy Recovery System (KERS): a system that is designed to
recover kinetic energy from the car during braking, store that energy and make
it available to propel the car”…
…”5.2.3 The maximum power, in or out, of any KERS must not exceed 60 kW.
Energy released from the KERS may not exceed 400 kJ in any one lap.
Measurements will be taken at the connection to the rear wheel drive train.”…

MGU: Design
Magnetic ,thermal and mechanics 3d calculation with resonances frequency analysis
are performed for ensuring maximum performances and reliability level

MGU: Thermal dynamic Design
On of the key design criteria is the thermal behaviour control under the mission profile.
The thermal working condition must be stable and inside the safe technologies limit also in the
worst cases of mission profile and coolant temperature.
The Motogenerator is designed to work with coolant fluid temperature until 140 ° so avoiding the needing of a
Separate dedicated cooling circuit

GLI ACCORDI INTERNAZIONALI
29th April 2009 Milan, Italy and Silverstone, UK
For Immediate Release
Magneti Marelli and Flybrid Systems to collaborate
on KERS energy storage for Motorsport
Italian Motorsport electronics specialist Magneti Marelli and British high-speed
flywheel specialists Flybrid Systems today announce the collaboration to
develop a new energy storage solution for the Kinetic Energy Recovery
System (KERS). The new product will deliver a high power electrical storage
system for hybrid racing cars capable of deep depths of discharge with no
performance degradation and a long service life.
The new product named Flywheel Capacitor consists of a high-speed carbon
fibre flywheel incorporating Flybrid® technology connected to a high-speed
electric motor generator using technology from Magneti Marelli, all managed
by Magneti Marelli’s control electronics.
The device works by applying to the electric motor generator the recovered
electrical energy captured from the vehicle during braking events. The energy
is stored into the Flywheel Capacitor by speeding up the flywheel. During the
acceleration events of the vehicle, the energy stored into the flywheel capacitor
is returned to the vehicle by transforming the kinetic energy of the flywheel into
electrical energy via the motor generator.
The Flywheel capacitor will not use chemical battery based energy storage
systems.
The first Flywheel Capacitor to be developed will have a specification of 60 kW
power and 600 kJ total storage capacity but the specification can be readily
adapted to any vehicle requirements. Both partners will draw upon extensive
experience with their own KERS products to deliver a working prototype in the
next few months.
The electric motor and flywheel will rotate at up to 60,000 RPM and the
flywheel will sit inside an evacuated chamber that includes special containment
features to ensure complete safety. A small electric pump will occasionally top
up the vacuum so that no regular maintenance is required.
State of the art magnetic design of the motor generator and high efficiency
electronics are expected to deliver round trip storage efficiencies approaching
80%. The device has a low cooling requirement and contains no flammable
materials. The complete flywheel capacitor including the associated electronics
is expected to weigh just 20 kg.
