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 selection of speed ratings allowing the generator to be selected to customer specific applications with various voltage requirements
•Can be also used as starter motor for the ICE
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
MOTOR SPECIFIC FEATURES
•Generator/Motor for parallel hybrid applications
•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
