METRO TRACTION MOTOR

This electric traction motor is widely used in metro systems for its durability and efficiency. It's built to handle the heavy demands of urban transit, such as frequent stops, high start-up torque, and heavy loads. The three-phase asynchronous motor, with a squirrel-cage rotor, is designed for both head and intermediate subway cars. It operates on ball bearings and delivers reliable torque, especially at low speeds, making it perfect for metro applications. Known for its long service life and energy efficiency, the motor helps reduce operational costs. It features a sturdy suspension system and a smooth electromagnetic torque transmission for consistent performance.

Some of the special features of the motor are:
  • Designed to withstand demanding conditions, including frequent starts and stops.

  • Offers good torque performance, especially at low speeds, which is beneficial for metro applications.

  • Known for its long service life and operational reliability.

  • Designed to operate efficiently, helping to minimize energy consumption and reduce operational costs.

  • Class II drive with support-frame engine suspension and support-axial reduction gear suspension.

  • Electromagnetic torque transmission via an articulated-drive coupling of longitudinal compensation, articulated cam mechanism.
