at Volvo Penta
" As a part of the Volvo Group's great
electromobility initiatives, Volvo Penta
has a solid technology foundation
to leverage. Marine electromobility,
however, has a unique set of requirements, "
explains Peter Granqvist, chief
technology officer of Volvo Penta.
" There are very specific considerations
that are of the utmost importance
around the installation environment,
safety, as well as the use case itself
plus the current lack of charging
infrastructure, " he said, explaining the
rationale for acquiring ZEM, which has
a particularly strong expertise in battery
technology and systems engineering
for marine e-propulsion.
ZEM drivelines use permanent-magnet motors from Danfoss Editron
A business division of Danfoss, Danfoss Editron specializes in
hybrid and electric powertrain systems for off-highway and marine
markets. It develops and manufactures power systems for
heavy duty vehicles, machines and marine vessels, based on
its unique synchronous reluctance assisted permanent magnet
(SRPM) technology.

" Volvo Penta's vision is to
become a leader in sustainable
power solutions, where
we are driving transformation
on land and at sea towards
a more sustainable society, "
explains Heléne Mellquist,
president of Volvo Penta.
" With this acquisition, we
are now able to offer driveline
solutions for marine
customers through ZEM and
also contribute to the broader
marine electromobility footprint
Heléne Mellquist, president of
Volvo Penta
through battery supply. It is a step forward in our transformation
and will also allow Volvo Penta to capture new opportunities. "
ZEM will remain operating under its current brand, and under
the leadership of Egil Mollestad, the long-time CEO of ZEM and
a recognized technology pioneer in the maritime sector. The
collaboration between Volvo Penta and ZEM is expected to
grow gradually. Although ZEM will continue to grow its battery
and complete driveline business, over time the two companies
will create complete packages together.
According to ZEM, it integrates Danfoss Editron electric motors
for the propulsion part of its systems. Based on synchronous
reluctance assisted permanent magnet (SRPM) or permanent
magnet synchronous machine (PMSM) technology, they are
liquid-cooled and designed to work in harsh operating environments,
typical in drivetrain applications. They can work both
as a generator or as a motor. Typically, they are paired with
Danfoss Editron inverters based on electronics from Semicron
in Germany.
