High RPM small dimension 100 kW Permanent Magnet Synchronous Generator (PMSG) manufacturing and performance testing

Abstract

Indonesia is an archipelagic country that is vulnerable to the effects of climate change. Climate change is mainly caused by global warming due to carbon emissions. Indonesia’s energy generation sector produces 34% of Indonesia’s total Green House Gas (GHG) emissions. So new ways of energy generation are needed to ensure the energy produced is clean from GHG such as renewable energy. For this reason, Hutama Karya is trying to develop core technology in the development of renewable energy in Indonesia. The core technology in question is the High RPM Small Dimension Permanent Magnet Generator. This PMSG has unique operating characteristics in the form of high RPM but low torque, making it suitable for application to renewable energy generation. The biggest challenge today is to ensure that the existing manufacturing technology in Indonesia is sufficient to produce the PMSG. Our findings indicate that manufacturing technology in Indonesia is sufficient to produce PMSG with 100 kW power capacity. It is indicated by the result of early testing that the generator can produce Electrical Coefficient (EC) value of 0.15.
