Copper Die-Cast Rotors for Traction Motors
Traction motors used in electric vehicles, electric buses, railway traction, locomotives, industrial vehicles and other mobility systems require high efficiency, high power density, strong dynamic performance and effective thermal management. KITRA's die-cast copper rotor technology can provide important advantages for induction and other copper-rotor-based traction motor designs.
Higher Efficiency & Lower Rotor Losses
Copper's high electrical conductivity helps reduce rotor I²R losses compared with conventional aluminium rotors. This can improve overall motor efficiency and help make better use of the available battery or electrical power.
High Power Density
Reduced rotor losses provide motor designers with greater flexibility to develop compact, high-power-density traction motors, where space and weight are important considerations.
Better Thermal Performance
Lower rotor losses can mean less heat generation, supporting improved thermal management during demanding acceleration, continuous operation and high-load conditions.
High-Speed Operation
Traction motors may operate across a wide speed range, including high-speed operation. KITRA copper rotors can be designed with the required mechanical integrity, concentricity and dynamic balancing for demanding high-speed applications.
Robust & Reliable Performance
Die-cast copper provides a robust squirrel-cage rotor construction. Combined with precision manufacturing and balancing, copper rotors can support reliable operation under frequent acceleration, deceleration and load variations.
Applications
KITRA copper rotors can be considered for traction motors used in electric cars, buses, commercial vehicles, railway traction, locomotives, industrial transport vehicles and other electric mobility applications.
