The New Controller Generation for MotorIntegration! i3: Maximum Performance, Minimal Installation Space

Thanks to advanced field-oriented control (FOC), the  i3 provides maximum performance in the smallest form factor. This makes it the perfect choice for applications in automation technology, robotics, medical devices, mobile systems, and many other fields.

Fully Equipped for Demanding Applications

Despite its compact design, the i3 offers the full range of functions required by today’s decentralized drive solutions:

• 4-quadrant operation
• Current, speed, and position control
• Integrated motion process unit with PLC functionalities
• Freely programmable stand-alone operation for motion intensive applications

With a built-in magnetic encoder and optional feedback options such as Hall or incremental encoders, maximum flexibility is guaranteed.

A Unified Concept with a Future

The i3 is based on a consistent, modular mounting concept. CANopen enables seamless integration into existing system architectures. The devices are also prepared for STO and UL certifications, making them suitable for safety-critical applications as well.

But the success story of the new controller generation is just beginning: In Q4/2026, the next model in the series - the i5 - will follow, offering an extended performance range of up to 90 A peak current while retaining the same proven architecture. This provides users with scalability, compatibility, and a unified software and operating concept across the entire product line.
