Data Sheet
EM-PME375-T150
Electric machine, permanent magnet external
FEATURES
• Synchronous Reluctance assisted Permanent
Magnet (SRPM) technology
• Extremely compact and robust structure
• Highest efficiency throughout the operation range
on the market (~96 %)
• Liquid cooled with plain water or water/glycol
mixture
• Low coolant flow required
• Allowed coolant temperature up to +65°C
• Up to IP65 enclosure class to maximize reliability
• Multiple mounting possibilities
GENERATOR SPECIFIC FEATURES
• Standard SAE flange mounting to match the diesel
engine connection
• Wide
• Can be also used as starter motor for the ICE
selection of speed ratings allowing the
generator to be selected to customer specific
applications with various voltage requirements
MOTOR SPECIFIC FEATURES
• Extended speed and torque capabilities compared
to standard PM motors from Danfoss reluctance
assisted permanent magnet motor technology
• Motor structure is designed to be able to produce
high starting torque: EM-PME motor can produce
instantly full torque to a non-rotating shaft
• Optimized speed range to meet the most common
gear ratios used in heavy mobile machinery
GENERAL
The machine is developed especially for demanding
applications. The design of these machines makes them
smaller, lighter and more efficient than conventional
products on the market.
The machine is designed to be shorter than normal motors
for applications where axial length is crucial parameter. The
machine is designed to be connected directly to the ICE
flywheel housing with part of the motor being inside the
flywheel housing further shortening the length of the motor.
TYPICAL APPLICATIONS
• Generator for diesel-electric/serial hybrid
applications
• Traction/propulsion motor
• Generator/Motor for parallel hybrid applications
