SynTRACS
Category: IT/Electrical
Developers: Mitsubishi Electric Corporation
Product Description:In recent years, decarbonization and the electrification of vehicles have been accelerating worldwide, and there is a demand for higher efficiency and resource conservation in motor systems for railway vehicles. Traditional systems use induction motors or PM motors, but the former faces the challenge of low motor efficiency, while the latter uses permanent magnets to achieve high torque, which poses environmental issues due to the large consumption of rare earth materials. To address these challenges and achieve resource conservation, SynTRACS has a maximum output of 450 kW using SiC inverters for railway vehicles, and does not use rare earth materials. SynTRACS is described as a motor system comprising a synchronous reluctance motor and SiC inverter for railways. The SynRM has both a high motor efficiency and max output power of 450 kW for railways without permanent magnets including rare-earth materials. SynTRACS can reduce the losses generated by each motor by 50% compared with conventional high-efficiency induction motors. Additionally, SynTRACS does not require circuit breakers to generate induced voltage at no-load. The technology can be applied to applications beyond railway vehicles, and being a rare-earth-free motor, it reduces geopolitical risks and contributes to a sustainable society.
