Battery Angle Grinder Multi-Mode Speed Control for Precise Cutting

The patent implements dynamic operating modes that allow the angle grinder to switch between different speed-power characteristics. The control unit provides multiple predefined operating curves (first, second, and third modes) with different maximum speeds and power outputs, enabling the user to select the appropriate mode for the specific cutting task. This dynamic adjustment resolves the contradiction by allowing high productivity when needed while maintaining precision when required.

The patent changes the operational parameters by introducing predefined operating modes with fixed speed-power characteristics. Instead of requiring the user to manually adjust the throttle lever to a specific position for precise cuts, the system provides preset modes (first, second, third) with optimized parameters for different cutting requirements. This eliminates the need for delicate throttle control and reduces user fatigue while maintaining cut precision.

The patent segments the operating characteristics into distinct predefined modes with different power plateaus and maximum speeds. The control unit is configured with multiple independent operating curves (first mode with lower power, second mode with medium power, third mode with highest power), each suitable for specific cutting applications. This segmentation approach improves adaptability while keeping the control system manageable through clear, discrete mode selections rather than continuous parameter adjustment.
