ZeroAvia Puts e-Propulsion Components for Aviation on the Market, Opens Manufacturing
Plant
ZeroAvia, a pioneering developer of electric propulsion technology
for aviation, has established a new manufacturing center in
Washington where it plans to produce some of the components
for its systems while also opening up the sale of them to others.
Two novel permanent magnet motors along with power electronics,
fuel cell and hydrogen products are among the components
being put on the market. A 660 kW max-power direct-drive motor
can reach speeds up to 2,200 rpm, and the HyperCore 900kW
modular motor is capable of speeds up to 20,000 rpm.
The HyperCore is a permanent magnet electric machine for applications
ranging from 900kW up to 10MW. The fully integrated
motor-inverter system is designed to be powerful, compact and
ultra-efficient with 4 silicon carbide inverters. Designed for high
altitude and unpressurized areas, its thermal, mechanical and
electrical integration are optimized for high reliability and long life
time by reducing cable weight, interfaces and coupling, connectors.
The inverters are fully equipped for high-speed bus communication
and a high degree of redundancy and availability.
ZeroAvia Motor is a high-efficiency machine developed to
support the company's ZA600 hydrogen-electric powertrain
for commercial aircraft up to 20 seats. The 660 kW 4x3 phase
permanent magnet synchronous machine 400-830 Vdc motor is
surface permanent magnet based with bidirectional operation,
specifically designed for direct drive installations mounted to a
propellor. The three phase AC current from the Inverter drives
the motor bidirectionally.
The stator core is divided into 4 sections to enhance fault tolerance
and allow higher input current from the inverters. The
motor is designed and produced following aerospace standards,
allowing a high-power density and reduced weight with advanced
thermal management. Optimized cooling allows for very efficient
heat transfer within the motor to allow it to run cooler and for longer.
It has a spline interface for mounting a gearbox or accessory
drive to the rear.
Certification work for the ZA600 engine for up to 20 seat aircraft
is underway, and the underpinning technology for the ZA2000
engine for up to 90 seat aircraft in advanced development. In
