Sinteg 550

The Rimac Sinteg 550 represents the state-of-the-art in integrated electric drive units (EDU). By consolidating the motor, inverter, and planetary transmission into a singular, thermally optimized architecture, it eliminates traditional cable harnessing and external cooling interfaces, drastically reducing parasitic weight and assembly complexity. The system is engineered to handle the extreme torque-vectoring demands of ultra-high-performance vehicles while maintaining a compact footprint. Technologically, the platform utilizes advanced silicon carbide (SiC) MOSFET-based inverters, which enable higher switching frequencies and reduced switching losses, critical for achieving high peak power without compromising efficiency. The motor design employs high-speed winding techniques and advanced magnetic flux management to deliver sustained high-RPM performance, effectively mitigating the common issue of power derating under heavy thermal load. From a procurement and engineering perspective, the Sinteg 550 is a strategic 'black box' solution that shifts the burden of software-hardware co-validation from the OEM to the supplier. Its modularity supports rapid integration into diverse vehicle architectures, making it a preferred choice for hypercar manufacturers looking to outsource complex high-voltage powertrain development while ensuring superior, track-proven reliability.
