IMFINITY Induction Motors

High-power Variable Speed Drives with SiC Technology.

S-PowerDrive is a state-of-the-art solution offering ultra-low harmonic distortion, compact design, low losses, and high power density for high-power process applications.

• IP21 or IP54 drive
• 6 pulse SiC or Active Front End (AFE) SiC versions
• Input 400 to 480 V or 525 V to 690 V

Key points of the S‑PowerDrive:

• High efficiency, highly compact
• Reduced losses and cooling requirements
• “Clean” drive with harmonics < 5% (AFE version, IEEE 519 standard)
• High power density and controlled thermal constraints
• Suitable for demanding applications: Process industry, Oil & Gas, Marine, Data Centers, high‑speed test benches
• Modular architecture facilitating integration
• Fast return on investment (ROI)
• Optimizes the overall system TCO (Total Cost of Ownership)

Energy performance and overall efficiency:

Energy optimization is a major challenge for industry. High-efficiency variable-speed solutions help reduce energy consumption, improve productivity, and lower the carbon footprint. When paired with the Dyneo+ motor, the S-PowerDrive forms a motor-drive package that maintains high efficiency across the entire operating range, including at reduced loads.

Ultra-compact design and reduced losses:

The S-PowerDrive is an ultra-compact drive designed for environments where space is limited, without compromising on performance.

• 30% smaller footprint compared to IGBT technology
• 60% lower power losses compared to IGBT technology
• Easier integration thanks to a modular design

“Clean” variable speed drive and harmonics control:

Harmonics management is essential for maintaining the quality of the power grid and minimizing the strain on upstream equipment. In the Active Front End (AFE) version, the S-PowerDrive:

• Limits total harmonic distortion to less than 5%
• Complies with the IEEE 519 standard
• Allows for smaller-sized transformers and upstream cables

Power density and controlled thermal constraints:

Thanks to SiC technology, the S-PowerDrive maximizes power density while ensuring reliability and performance, even at high switching frequencies

• Loss reduction
• Optimized thermal management
• Minimal derating at high frequencies

Modular architecture and flexibility for OEMs:

• Wide power range
• Quick commissioning
• Simplified maintenance & diagnostics
• Connectivity compatible with most architectures
• Modularity adaptable to the specific requirements of each application
