Cordless garden tools power and motor-control application

Efficient battery-to-motor power architecture for cordless garden equipment

Modern cordless garden tools require high peak torque, long operating time and dependable protection in compact, thermally constrained enclosures. The power architecture combines a removable lithium-ion battery pack, a low-loss anti-reverse connection stage, a three-phase MOSFET inverter and an integrated controller-and-driver platform. Together these blocks support efficient BLDC motor operation, fast transient response, controlled startup, regenerative-current handling and protection against overcurrent, undervoltage, locked rotor and abnormal temperature.

About the solution

Battery-powered three-phase motor control optimized for torque, runtime and protection

A removable lithium-ion battery pack feeds the drive through a low-loss anti-reverse connection stage before the three-phase inverter converts the DC bus into controlled phase currents for the BLDC motor. The controller and driver coordinate PWM timing, current measurement, startup, commutation or field-oriented control, regenerative-current behavior and fault shutdown. The architecture is designed to deliver high starting torque and fast load response while protecting the battery, inverter and motor under jammed-blade, locked-rotor and thermal-stress conditions.

Scalable across lawn mowers, trimmers, blowers, chainsaws and compact outdoor equipment

The same functional platform can be adapted for low-voltage handheld tools and higher-voltage, higher-power garden equipment. Battery voltage, inverter current, MOSFET package, cooling method, sensing strategy, motor-control algorithm and protection thresholds can be scaled for grass trimmers, hedge trimmers, leaf blowers, lawn mowers, pruning tools, chainsaws, tillers and other cordless outdoor products.

Device categories aligned with the battery interface, inverter bridge and motor-control path

Battery-pack protection devices, low-resistance anti-reverse MOSFETs, three-phase inverter MOSFETs, half-bridge and three-phase gate drivers, current-sense amplifiers, power supervisors, motor-control MCUs and auxiliary regulators provide a practical semiconductor platform for efficient, compact and robust garden-tool designs.
