Axle With Electric Motor

For bus manufacturers and transit operators, an axle with electric motor is more than a part-it's the cornerstone of a high-performing electric bus. The EA2100N 13T Electric Portal Axle reimagines this integration, combining dual permanent magnet synchronous motors (PMSM), robust gearing, and intelligent controls into a single axle engineered for 10.5-18m articulated and double-decker buses. Let's explore why this axle with electric motor is a game-changer for heavy-duty transit.

Dual PMSM Motor Setup: This axle with electric motor utilizes two permanent magnet synchronous motors, each capable of 2×580 N·m peak torque. This configuration guarantees smooth acceleration, even for fully loaded 18m articulated buses.

High Torque & Speed Capacity: With a system output torque of 21,552 N·m and a maximum motor speed of 8000 r/min, it handles heavy loads and diverse terrains effortlessly.

IP68 Environmental Protection: Rated IP68, this axle with electric motor is dust-tight and waterproof, making it dependable in rain, snow, or dusty urban settings.

 

Low-Floor Design Compatibility: Its portal architecture enables a low-floor layout, enhancing passenger accessibility and interior safety-a must for modern transit buses.

 

E-mark Certified Reliability: The axle with electric motor is mature and stable, holding E-mark certification-ensuring compliance with strict European safety and performance standards for transit vehicles.

 

Tailored for Articulated & Double-Decker Buses: Its robust build makes it the ideal choice for 10.5-18m articulated and double-decker buses, where space and power are both critical.

 

 

Long-Life Electronic Differential System (EDS): The proven EDS ensures tire change mileage exceeds 100,000 km, slashing maintenance costs and downtime for fleets.

 

Efficient Power Transfer: The integrated axle with electric motor design minimizes energy loss, translating to better range and lower operational costs for bus operators.

Articulated Buses (10.5-18m): Its high torque and low-floor design make it perfect for these long, passenger-dense vehicles, ensuring smooth rides and easy boarding.

Double-Decker Buses: With a 13,000 kg rated axle load, it supports the extra weight of a second deck, while the low-floor front section prioritizes accessibility.

Urban & Suburban Transit Routes: Whether navigating busy city streets or climbing suburban hills, the axle with electric motor delivers consistent, reliable performance.

 

Creating a dependable axle with electric motor requires rigorous innovation:
Extreme Climate Testing: The EA2100N is tested from -40°C to 85°C, ensuring it performs in any climate-from frigid winters to scorching summers.
Advanced Materials: Gears and motor components use hardened steel and lightweight alloys, balancing strength and efficiency for the axle with electric motor.
Intelligent Control Software: In-house software optimizes torque distribution and regenerative braking, maximizing efficiency and reducing wear on the axle with electric motor.

Mass-producing the EA2100N axle with electric motor demands unmatched precision:
Automated Assembly: Robots assemble components to ±0.01mm tolerances, ensuring every axle with electric motor performs identically.
Comprehensive Quality Checks: Every axle undergoes IP68 waterproofing tests, torque validation, and noise analysis before leaving the factory.
Sustainable Production: Recycled materials and energy-efficient machinery are used, aligning with the eco-friendly ethos of electric transit.

1. Can the EA2100N axle with electric motor be used in non-articulated buses?

While optimized for articulated/double-decker models, it can be adapted for other heavy-duty buses-reach out for customization options.

2. How often does the EDS in the axle with electric motor need maintenance?

The EDS is low-maintenance; we recommend inspecting it every 20,000 km, but it typically lasts beyond 100,000 km with proper care.

3. Does the axle with electric motor support regenerative braking?

Yes, its integrated software manages regenerative braking, capturing energy during stops to extend range.

4. What warranty does the EA2100N axle with electric motor come with?

We offer a 3-year/300,000 km warranty, a testament to our confidence in its durability.

5. Is the axle with electric motor compatible with different battery voltages?

It's rated for 540 VDC, but we can customize voltage for specific fleet requirements.

6. How does the axle with electric motor handle heavy loads on steep inclines?

With 21,552 N·m of torque, it easily climbs steep grades even at full load-no performance compromise.

Our EA2100N axle with electric motor is more than a component; it's a solution for transit operators seeking reliability, efficiency, and accessibility. Its integrated design, E-mark certification, and specialization for articulated/double-decker buses make it a standout for modern electric transit.
