The electric machines have been developed especially for heavy duty, marine and transportation
applications. They are more reliable, smaller, lighter and more efficient than conventional products
on the market.
Typical applications of the electric machines are:
Motor (electric propulsion) and generator for hybrid marine vessels or mobile work machine
and bus parallel hybrid applications.
Traction motor and generator for electrical or hybrid electrical mobile work machines or buses.
The electric machines feature Syncronous Reluctance assisted Permanent Magnet (SRPM) motor
technology, having several advanced features:
Extremely compact and robust structure.
High efficiency throughout the operation range.
Liquid cooling with water/glycol mixture.
Low coolant ow required.
High allowed coolant temperature.
IP65 enclosure class to maximize reliability.
Multiple mounting possibilities.
Extended speed and torque capabilities compared to standard PM machines.
Machine structure designed to be able to produce high starting torques (instant torque to
non-moving wheel).
Optimized speed range to meet most common gear ratios used in heavy mobile machinery.

The electric machines have several frame models (sizes) to be the optimal solutions for several
applications. They also have options for shaft type, attachment interface, bearings, connection
box attachment, rotation sensors and temperature sensors.
