Engineering Highlights
1. Sine-Wave Drive Technology
Using sine-wave PWM modulation, the controller ensures smooth three-phase current flow, eliminating the high-frequency vibration typical of square-wave systems. Every throttle movement translates into fluid, organic power delivery.
2. Vector Control Algorithm
By applying vector decomposition and coordinate transformation (Clark & Park transforms), the controller separates motor current into torque and flux components, controlling each independently. This enables rapid, precise torque delivery and unmatched smoothness across the entire speed range.
3. High-Frequency Sampling & Real-Time Response
Operating at a sampling rate of up to 20 kHz with a high-speed DSP core, the controller responds within milliseconds. Whether under sudden acceleration or cornering dynamics, it maintains stable, predictable power delivery.
4. Thermal Management & Safety Logic
The controller features multi-level thermal protection and self-adaptive learning algorithms that dynamically adjust current limits based on temperature. Integrated fault diagnostics ensure reliability and longevity under any riding condition.
Intelligence Meets Experience
The YVOLT sine-wave vector controller is not just an engineering achievementβitβs a tuner of emotion.
It bridges the precision of electric power with the fluidity of combustion engines, blending silence, immediacy, and human connection.
When rider intent, motor dynamics, and control intelligence unite, true harmony between technology and motion emerges.
