The power tool industry is undergoing a profound technological shift, marked by the “Cordless” and “Brushless” waves. The market for lithium-ion tools demands ever-increasing runtime and performance. Competition in the professional-grade sector is fierce, with core competitiveness defined by powerful output, high battery endurance, and durability under harsh conditions. The industry’s pain points for motors are clear: 1) High Power Density: Delivering maximum power within the limited volume and weight of a handheld tool. 2) High Overload Capacity: Withstanding the instantaneous high-load impacts (stall) encountered during drilling or fastening. 3) High Efficiency: Increasing the work-per-charge (extending battery life) and reducing heat generation during prolonged heavy use. 4) Long Life & Reliability: Enduring high-frequency vibration, dust, and debris.
AKT Product Solution
AKT provides efficient, powerful solutions for modern power tools, centered on high-power Brushless DC Motors (BLDC).
- High Power Density & Efficiency Solution:
This is the key advantage of BLDC motors over traditional brushed motors. Our high-power BLDC motor series (e.g., 57mm, 60mm frames) utilizes high-grade, high-temperature magnets, low-loss silicon steel, and optimized winding technology to achieve exceptional power density. Their high efficiency (outperforming brushed motors across a wide speed and load range) significantly reduces heat and maximizes battery runtime. The brushless design fundamentally eliminates brush wear and sparking, enabling maintenance-free operation and a longer tool lifespan. - High Torque & Impact Load Solution:
Power tools frequently experience stalls and impact loads. Our BLDC motors are designed with extremely high peak torque capabilities (several times the rated torque). For tools requiring immense torque, such as garden tools or heavy-duty wrenches, our BLDC motors are paired with high-strength, high-torque planetary gearboxes. Our planetary gearboxes feature high-strength alloy gears and full-needle bearing designs to withstand high-impact shock loads, ensuring the durability of the powertrain. - Intelligent Control Solution:
The performance of a brushless tool is critically dependent on its driver (controller PCBA). AKT provides customized BLDC driver solutions (PCBA-based). Our algorithms are specially optimized for tool applications, enabling: instantaneous high current output (for impacts), precise speed/torque control (e.g., electronic clutch), constant power output, and comprehensive over-current/over-temp/under-voltage protection, ensuring tool performance and safety under extreme conditions.
Engineering & Customization Capabilities:
We work closely with tool manufacturers to provide deeply customized powertrains. This includes custom motor dimensions to fit tool housings, optimized windings for specific battery platforms (e.g., 18V/36V), and integrated planetary gearbox modules that incorporate the driver, switch, and sensors.
Typical Application Equipment Examples
- Cordless Drills / Impact Wrenches:
These tools demand extremely high instantaneous peak torque and efficient power conversion. Our high-power BLDC motor + high-current driver system is engineered to withstand high-intensity impacts and stalls, while its high efficiency ensures more work per charge. - Cordless Angle Grinders:
Grinders operate under continuous heavy load during cutting and grinding, demanding high continuous power and excellent thermal management from the motor. Our BLDC motors (e.g., 60mm, 86mm series) offer superior heat dissipation and constant torque characteristics. Paired with our planetary gearboxes, they deliver high-torque cutting power without overheating or throttling. - Electric Garden Tools (Chainsaws / Shears):
These applications require high torque to cut through hard wood. Our BLDC motor combined with a high-ratio planetary gearbox forms a high-torque, high-efficiency power module. It delivers robust power and is significantly quieter, cleaner, and maintenance-free compared to traditional gasoline engines.
Summary
Performance is the lifeblood of power tools. AKT is not just a motor manufacturer but an engineering partner in enhancing product performance. We collaborate closely with tool manufacturers to provide deeply customized, integrated solutions of BLDC motors, high-strength planetary gearboxes, and drivers. Using advanced electromagnetic and thermal simulation, we jointly meet the market’s demand for higher performance, longer runtime, and better ergonomics.
