In 1995, Indonesia began operating the first electric train manufactured by local companies. This EMU was created by a consortium of state-owned enterprises in Indonesia (PT. INKA (Persero), PT. LEN (Persero) and PT. PINDAD (Persero)) with a consortium Belgien - Nederlandsch - Holland Electric (BN - Holec). PT. PINDAD (Persero) in charge of transferring technology in traction motor design. KRL Jabodetabek (Jabodetabek EMU (Electric Motor Car Unit)) is a rail-based transportation that serves the area with operation region covering the Capital State and several surrounding cities (DKI Jakarta, Bogor City, Depok City, Tangerang City, and Bekasi City). KRL BN-Holec is the first electric trains manufactured in Indonesia. This KRL BN-Holec was designed to meet the passenger demand back at 1995, however in the early year 2000 the passenger demand has already increased significantly. Therefore, a new design of motor traction suitable for KRL BN-Holec which meet the new passenger demand is needed. In this paper, a new design of traction motor 180 kW for KRL BN-Holec application is proposed. By using the proposed design, the power density can be increased without sacrificing the performance. It can be shown that the experimental result proves that the proposed design meet the performance required.
