Solution Features
Our EA1100K employs dual PMSM motors, each delivering peak power of 90 kW and continuous rated power of 55 kW. The torque output reaches 350 N·m per motor, while the axle supports a rated load of 9,000 kg. With a steering angle of ±18° and a maximum wheel speed of 540 r/min, it is engineered for smooth control on guided transit routes.
From a practical perspective, this electric motor and axle allows virtual metro vehicles to maintain consistent traction, precise steering, and safe braking through air disc systems. IP67 protection further safeguards the motors in varied weather and operating environments.
Product Advantages
Decision-makers in rail-based transit projects look for both reliability and efficiency. Our EA1100K offers:
Durable performance – PMSM motors with IP67 protection withstand urban operating conditions.
Energy efficiency – Optimized motor control improves energy use per kilometer, lowering operating costs.
Integrated design – This electric motor and axle streamlines vehicle assembly, reducing system complexity.
Safety focus – Air disc brakes enhance braking stability, vital for passenger-carrying rail systems.
These benefits provide customers with confidence in long-term service performance.
Product Applications
The design of our EA1100K is dedicated to virtual rail metros with rubber-tire systems. This application demands high axle load capacity, accurate steering, and dependable power delivery. This electric motor and axle fits these needs by enabling quiet operation, reduced emissions, and reliable urban transit performance.
Technology & R&D
Our R&D teams work extensively to refine each element of EA1100K. Thermal management of the PMSM motors, optimization of gear ratio (17.55), and validation of torque output are all tested under simulated metro conditions. Real-world trials in urban transit environments confirm efficiency, ride comfort, and system durability.
The result is an electric motor and axle solution that performs predictably in the demanding, high-frequency cycles of metro operation.
Manufacturing Excellence
Production facilities follow strict standards to ensure quality and consistency. From precision machining to motor assembly and end-of-line axle testing, each process step verifies compliance with international transit requirements.
Every electric motor and axle undergoes durability checks, including steering simulations and protection testing against dust and water. This gives customers assurance that each unit is validated before entering metro service.
FAQ
Q1: What makes a steering electric portal axle different from a regular electric axle?
The steering portal axle integrates steering capability, essential for rubber-tire metro axles, unlike fixed-position electric drive axles.
Q2: Can the gear ratio of the EA1100K be modified?
Yes, adjustments can be made to fit specific requirements of electric transit axle systems.
Q3: How is maintenance handled for the electric motor and axle?
Routine inspections of brakes and lubrication are recommended, though the sealed design minimizes regular servicing compared to traditional systems.
Q4: Is EA1100K suitable for heavy rail?
No. It is specifically optimized for virtual metro systems with rubber-tire axles, not for heavy rail applications.
Q5: How does IP67 protection help in daily operation?
It prevents dust and water ingress, making the EV portal axle more reliable across different climates.
Q6: What is the rated load capacity?
The axle supports up to 9,000 kg, aligning with requirements of rubber-tire metro drive axle systems.
