Copper Rotor Cage: The Key to Efficiency in our Traction Motors

Modern rail vehicles require motors that not only deliver high power but also stand out for their exceptional efficiency and reliability. The ability to operate in extreme conditions, such as frequent overloads resulting from acceleration and braking cycles, is crucial. In response to these challenges, we use a copper rotor cage in its traction motors.

Why Copper Matters

The use of a copper rotor cage is one of the most significant factors in improving motor efficiency. Due to its excellent conductivity, copper minimizes energy losses, which directly translates into higher efficiency for the entire vehicle drive system. Furthermore, this solution provides better starting parameters and allows the motor to operate smoothly under overload conditions. As a result, our motors are capable of withstanding the intense loads characteristic of rail transport, guaranteeing long-term, trouble-free operation.

Individual Approach and Design Optimization

Every motor is designed based on detailed customer requirements, allowing for the optimization of the design in terms of both cooling and operating parameters. This process includes precise electromagnetic circuit calculations, which form the basis for designing individual motor elements, including the cooling systems.

The Importance of Optimal Cooling

One of the key elements influencing motor performance is an appropriately designed cooling system. Electromagnetic circuit calculations allow for the design of elements such as air inlets, outlets, and the fan to ensure proper airflow. The fan is selected based on the required speed and capacity of the cooling air, as well as the motor's rated speed. The correct selection of the fan is crucial for achieving optimal operating parameters and ensuring the long-term reliability of the motor.
