For harsh conditions, like salty air in marine applications, it is recommended to check the
surface treatment possibilities with the factory.
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 machines and bus
parallel hybrid applications.
•
Traction motor and generator for electrical or hybrid electrical mobile work machines or buses.
The electric machines feature Synchronous 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 flow required.
•
High allowed coolant temperature.
•
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 machine
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.
