Smart Cordless Brushless String Trimmer

Professional gardening tools are evolving toward intelligent, connected cordless platforms that boost productivity while reducing size, weight, and maintenance requirements. As landscaping companies face rising service demand and labor shortages, operators need trimmers that deliver consistent, high-efficiency performance and automatically adapt to different cutting conditions.

This next-generation cordless string trimmer integrates high-efficiency power conversion, intelligent motor control, and smart connectivity into a single design. It is built around a next-generation GaN-based 3-phase BLDC motor controller with switching frequencies of up to 100kHz, delivering higher efficiency, lower heat loss, reduced cooling requirements, and a smaller form factor. A high-performance motor control MCU runs sensored field-oriented control (FOC) together with AI/ML-based adaptive control that automatically detects cutting-line length and optimizes line feeding for consistent cuts and maximum operator efficiency. Integrated Bluetooth^® Low Energy (LE) connectivity enables real-time monitoring, usage tracking, fleet management, and over-the-air firmware and AI updates. In addition, the modular platform design can be scaled to meet a wide range of customer requirements.

System Benefits:

• GaN-based 3-phase BLDC motor controller with high-frequency switching of up to 100kHz, delivering high efficiency, low heat loss, reduced cooling requirements, and high power density in a compact design
• Upgraded MCU with sufficient processing capability to run both motor control (FOC) and AI/ML adaptive algorithms
• Bluetooth LE connectivity for asset tracking, real-time monitoring, and over-the-air firmware and AI updates
• Modular platform design that is scalable and adaptable to a wide range of tool requirements
