The Institute “Electrical Energy Conver-
sion“ belongs to the Faculty (Depart-
ment) of “Electrical Engineering and
Information Technology“ at Darmstadt
University of Technology. It has a long
lasting tradition, because it arose already
in 1919 from the former Institute „Electri-
cal machines“, that was founded by
Erasmus Kittler, the worldwide first
university professor for Electrical Engi-
neering (1882). Under the direction of
Prof. Dr.-Ing. habil. Dr. h.c. Andreas Binder
lectures, tutorials, laboratories und
excursions with the focus on electrical
machines, transformers and actuators,
drive systems and electrical trains and
E-drive systems for cars are offered.
Research at the institute
Currently there are 15 research assistants
(PhD) and 1 post doctor doing researches
with the main focus in the following
fields: high-speed drives, magnetic levita-
tion, bearing currents at inverter supply,
drive components for the electrical trac-
tion (train, car), linear motors and direct
drives, generators for wind and hydraulic
energy, numerical design of electric
machines and mechatronic drive systems.
Equipment
The institute is equipped with two lab
halls with total 1200 kVA-Transformer-
supply. The labs have load facilities for
electrical machines up to approx. 250 kW.
Rotary converters can supply machines
up to 40kVA @ 400/800 Hz or 200 kVA
@ 200 Hz. A high-voltage-transformer
offers a power up to 250 kVA with
3/5/6 kV. The mechanical workshop can
manufacture prototype of E-motors up
to 100 kW while the electrical workshop
develops control modules, measuring
adapters and makes modification of
inverters etc.
