Energy Generation

Applications / Energy Generation

e+a motors are ideal for use in direct drive turbo generators.

Since 2008 e+a Elektromaschinen und Antriebe AG has been manufacturing components for mobile (shipborne, truck, railroad and airborne) and stationary (land-based) energy generation; applications include ORC, sCO2, micro-turbines, turbo-expanders, automotive range extenders, man-portable generators, gas turbine engine driven, etc.

Challenges:

Winding design for high-performance machines
Generator and frequency converter parameter adjustment (clock frequency, maximum output frequencies…)
Maximize efficiency

Expertise:

Successful projects in applications > 1000kW
Proprietary winding design significantly reduces losses at high frequencies
PM rotor technology enables prodigious torque at very high speeds with maximum efficiency
Development and manufacture of proprietary CFRP sleeves for high tip speeds (280 m/s)
Compatibility with commercial refrigerants verified by laboratory testing
e+a and customer joint development of suitable cooling processes for large rotors & stators
Joint development of shaft-rotor assemblies satisfying rotor dynamic constraints

With the continued successful implementation of projects in decentralized energy generation, e+a can support customers with applications in both Low Voltage and Medium Voltage regimes, and with output powers up through and exceeding 1000kW.
