Industrial-grade intelligent drive solutions
This motherboard is specially designed for Angle grinders, integrating three core technologies: wide voltage adaptive, intelligent start-stop control, and multiple safety protections. It is compatible with 110V/220V dual-voltage environments and meets the demands of industrial scenarios in different regions around the world. With a high power output of 1700W and a rotational speed range of 10,000 to 11,000 RPM, it can easily handle high-intensity operations such as metal cutting, stone grinding, and concrete slotting, earning it the title of "the intelligent heart of a craftsman's work platform".
Technical parameters
Dual-voltage intelligent switching system
It adopts a self-developed voltage recognition chip and automatically matches 110V/220V input power supply without the need for manual adjustment. When an abnormal voltage is detected (such as below 180V or above 260V), the under-voltage/over-voltage protection mechanism is triggered. The power will be automatically cut off and an alarm will sound within 3 seconds to prevent the risk of motor burnout.
Dual-mode control of soft start and emergency stop
Soft start mode: Through PWM pulse width modulation technology, it achieves 0-100% stepless speed regulation start-up, reducing mechanical shock by 40% and extending the service life of carbon brushes/bearings by more than 30% (measured data).
Emergency stop function: Complies with the IEC 60745 safety standard for electric tools. Power will be cut off within 0.1 seconds after the switch is released to ensure operational safety.
Heat dissipation and thermal management optimization
Power devices (such as IGBT modules) equipped with an aluminum heat sink and a centrifugal fan combination can keep the temperature within 65℃ under full-load conditions, improving the heat dissipation efficiency by 50% compared to traditional designs and ensuring the stability of continuous operation.
Performance parameters
Electrical characteristics
Input voltage: AC220V (compatible with 110V), working current: 9A, power factor ≥0.95, efficiency ≥92%. With a nominal power of 1700W, it has been verified through actual working conditions that it can stably output a speed of 10,000-11,000 RPM, and the cutting efficiency is 20% higher than that of similar products.
Protection mechanism
It is equipped with built-in overcurrent protection (trigger threshold 12A), short-circuit protection (response time ≤10ms), and locked rotor protection (automatic shutdown after 3 seconds). Combined with a waterproof and dustproof design (IP54 grade), it is suitable for harsh working environments.
