High-Voltage Motor Controller for 8m+ Electric Buses Up to 260kW Peak Power IP68

Product Overview

Designed specifically for electric buses over 8 meters, this high-voltage motor controller delivers stable, high-power traction performance for urban and intercity public transportation. Built with advanced 1200V IGBT power modules, it supports multiple power configurations to match different vehicle platforms. Precise torque and speed control, combined with robust protection and IP68 sealing, ensure reliable operation in harsh environments and heavy-duty driving cycles.

Vehicle Compatibility & Functional Configuration

• Compatible models:
  Electric buses over 8m

• Control functions:

  • Torque control

  • Speed control

  • Active discharge

  • Anti-slippage / anti-rollback

These features make it suitable for long-tail applications such as traction motor controller for large electric buses and anti-slip motor inverter for public transit vehicles.

Electrical & Power Performance

• IGBT power module: 450A / 600A / 800A (1200V)

• Control voltage: 12V / 24V (range: 18–32V)

• Rated DC voltage: 600V (range: 400–750V)

• Peak main drive output options:

  • 160 kW / 325 Aac

  • 230 kW / 425 Aac

  • 260 kW / 540 Aac

The wide DC voltage range and scalable peak power support various drivetrain architectures, ideal for 600V electric bus traction inverters and high-power EV motor controllers.

Control Accuracy & Driving Precision

• Torque control accuracy:

  • ≤ ±5 Nm (below 100 N·m)

  • ≤ ±5% (100 N·m and above)

• Speed control accuracy:

  • ≤ ±10 rpm (0–1000 rpm)

  • ≤ ±1% (1000 rpm to maximum speed)

High precision improves acceleration smoothness, energy efficiency, and passenger comfort in large electric buses.

Mechanical Design & Environmental Reliability

• Dimensions: (375 × 285 × 162) mm ±2

• Weight: 10 kg ±0.5 kg

• Ingress protection: IP68

• Operating temperature range: −40°C to +85°C

The compact structure and full sealing design enable reliable operation in wet, dusty, and extreme-temperature conditions, supporting searches like IP68 motor controller for electric buses.
