Design of Traction Motor 100kW for LRT Rolling Stock in Jabodebek – Indonesia

Inter-city mobility in Jakarta, Indonesia’s Capital City, is growing every year. The construction of mass transportation modes is expected to reduce travel time caused by congestion. The LRT (Light Rapid Transit) which was built in Jabodebek (Jakarta – Bogor – Depok – Bekasi) is expected to reduce travel time between cities around Jakarta. PT Pindad was requested by PT INKA as a rolling stock builder to provide an induction type of traction motor for LRT. To fulfill the requirement the power capacity of the motor is decided at 100 kW per motor and that needs 16 traction motors per trainset with 6 cars integrated. The maximum service speed of the vehicle designed at 80 km per hour and the maximum speed of a vehicle is 90 km per hour. The design also considers the diameter of the wheel in new condition or worst condition to decide the maximum speed of motor.
