Elaphe Applies Its In-Wheel Propulsion Systems to Growing Roster of EV
Platforms
Innovative electromagnetic topology and a full-systems approach are key to Elaphe in-wheel propulsion design
Slovenian in-wheel propulsion developer Elaphe, a designer of
innovative electromagnetic topologies for pushing the limits of
power density, is working on several projects designed to bring
new levels of performance to the EV market. A major project involves
its joint venture with power electronics specialist McLaren
Applied targeting automotive applications, other are its work to
develop a 350-watt gearless hub motor for electric scooters and
manufacturing its systems for solar EV company, Aptera.
Having demonstrated
energy efficiency of over
97% on vehicles such as
the Lightyear Zero and
Aptera, Elaphe's in-wheel
technology has achieved
torque densities up to
460 Nm/liter and 100Nm/
kg. In its partnership with
McLaren Applied, Elaphe
joins its technology with
the supplier of inverters for
the McLaren P1 in 2012
and Formula 1 and Formula
In January, the two companies announced they are collaborating
to provide an in-wheel propulsion system that couples McLaren
Applied's innovations in inverter technology with Elaphe's
cutting-edge direct-drive in-wheel motors and vehicle controls.
McLaren Applied's silicon carbide
IPG5 inverter
E since 2013. McLaren Applied has brought this technology to
the wider automotive market with its 800V Silicon Carbide (SiC)
inverter, IPG5. It offers unrivalled gravimetric and volumetric
power density of 90kVA/kg and 130kVA/L respectively, variable
switching frequency, and efficiency of up to 99%.

The scooter project aims
at developing a modular
3-wheel electric kick scooter
for urban and suburban
mobility. Elaphe is involved
in motor design, joining
forces with another Slovenian
high-tech manufacturing
company, Domel, on
building a 350W gearless
hub motor. What is special
about this motor compared
to other Elaphe motors is
its size, mass and power. It
is much smaller and lighter
and less powerful compared
to other Elaphe motors.
Transversal flux design for lightweight
motor in kick scooter
This application required a different design approach, different
electromagnetic topology, so Elaphe took one of their own old
TFM designs from the drawers and improved it with a few recent
developments, making this motor a superior one in terms of
power, weight and energy efficiency for the specific vehicle type.
There are several technical reasons for TFM superiority agains
