KESSLER COOLMOTION®
The COOLMOTION® technology optimizes efficiency to a maximum.
- KESSLER is the innovation engine behind state-of-the-art
direct drive technology and is renowned for powerful and energy-efficient
motors with high torque density and top reliability even in high-demand
applications. Practically-based simulations and individual customer
calculations are a prerequisite for the development excellence of KESSLER
motors.
The inverter-optimized COOLMOTION® motors are recognized for their low-loss design and enhanced heat dissipation. Innovative modifications of the motor components have enabled us to reduce the rotor and stator losses by 25 %. Special construction measures have resulted in significantly enhanced heat dissipation.

DRIVE SYSTEMS
Drive Technology / ADRENALINE
- The ADRENALINE propulsion system is equipped
with a KESSLER direct drive – based on innovative
COOLMOTION® technology with an integrated
frequency converter. The converter and motor are
perfectly matched modules and are available individually
as an option. The motor is powered by a fail-safe
storage system from our own battery design section
and offers very high energy density and durability.
The skipper can monitor key parameters by means
of the on-board computer, developed specially by
KESSLER energy, which displays the speed, the
state of charge and the range. Maximum safety is
guaranteed by a monitoring system consisting of an
interlock and insulation monitoring as well as the
state-of-the-art high-voltage system based on the
latest e-mobility standards.
Product focus: Direct drive system for electric boats
- 1. KESSLER energy on-board computer (HMI) with
display of speed, charge status and range.
2. High-voltage battery systems for maximum performance.
3. High-voltage electric motor, based on state-of-the-art synchronous motor technology with an integrated frequency converter. Scalable system, i.e. the drive systems are also available for different performance classes. Thanks to our own in-house battery cell configuration section, we can cater for all sizes and capacities. The converter and motor are perfectly matched to the application.
4. KESSLER energy supplies the complete system with the wiring, charging technology and battery management, and also supports customers during installation on site.
