Dreams Come True.
Motors are the core of future transportation.
Containing smaller, lighter, and more efficient motors is the most important competitiveness of the future transportation.
The vision of KSEP is to become a leading developer of high efficiency electric motor.
Since 2013, we have been developing motors that satisfy our customers.
We are leading the urban air mobility(UAM) industry with our optimal technology.
The motors developed by KSEP and clients perform the best performance in various fields.
KSEP promise to work with our clients by developing the best motors that will meet the needs of our clients as a market leader of future transportation.
KSEP is on the way
