Imagine a future where cars no longer rely solely on the roar of internal combustion engines, but glide silently through urban landscapes. This vision depends on efficient and reliable electric drive systems, with Valeo's 48V brushless motor emerging as a powerful "heart" of this transformation. This advanced motor not only delivers significant fuel economy improvements for hybrid vehicles but also powers light electric vehicles, ushering in new mobility paradigms.

Valeo's 48V motor represents a reversible unit that integrates power electronics including inverters, transforming it from a simple power output device into an intelligent energy management system. Its standout feature lies in architectural flexibility, enabling seamless integration across various hybrid systems beyond conventional P0 (belt-driven) configurations.

The motor's adaptable design allows placement at multiple critical points:

• Transmission input shaft (P2 external or P2.5 internal configurations)
• Transmission output shaft (P3 position)
• Rear axle via dedicated transmission (P4 eDrive system)

This modular approach empowers automakers to select optimal motor placement based on vehicle platform requirements, optimizing performance and efficiency across mild hybrid, full hybrid, and plug-in hybrid applications.

In hybrid implementations, Valeo's 48V motor demonstrates remarkable synergy with internal combustion engines. WLTP (Worldwide Harmonized Light Vehicles Test Procedure) cycle testing reveals 15% better fuel economy compared to conventional start-stop systems. This translates to tangible benefits:

• Reduced operating costs for consumers
• Lower carbon emissions for environmental protection
• Simplified compliance with tightening global emissions regulations

Beyond hybrid vehicles, the 48V motor finds application in light electric mobility solutions. When paired with specialized transmissions (eDrive systems), it powers:

• Electric two-wheelers and three-wheelers
• Compact urban quadricycles
• Last-mile delivery vehicles

These applications address growing urban transportation needs while reducing noise pollution and improving air quality in densely populated areas.

Valeo's technological leadership manifests in several key design features:

• Modular Platform: 48V architecture supports multiple hybrid configurations with reduced development timelines
• Hairpin Winding: Enhances power density within compact dimensions
• Adjustable Stack Length: Enables voltage and power customization for diverse applications
• Integrated Connectors: Combine power and signal transmission for simplified installation
• PMSM Technology: Permanent magnet synchronous design delivers 92% operational efficiency
• High-RPM Capability: 21,000rpm maximum speed enables dynamic performance

The motor offers three cooling configurations matched to power requirements:

• Air-Cooled (8 kW peak): Cost-effective solution for mild hybrid and light EV applications
• Oil-Cooled (15 kW peak): Axial cooling circuit enables compact packaging for medium hybrids
• Liquid-Cooled (25 kW peak): Maximum thermal management for performance-oriented applications

This graduated approach ensures optimal thermal performance across diverse operating conditions while maintaining reliability.

As automotive electrification accelerates, 48V systems are poised to play an increasingly vital role in bridging conventional and fully electric powertrains. Valeo's technological advancements in this domain provide automakers with flexible solutions to meet evolving efficiency targets and environmental regulations, contributing to sustainable mobility solutions worldwide.
