High Branch Saw Motor Control Solution
Description
With the advancement of science and technology, the popularization of mechanized operations is aimed at landscaping, courtyard maintenance, road cleaning, forest fire prevention, and harvesting by dealers. Golden Triangle Group has launched a high-branch saw motor control solution, which has the advantages of high power, low vibration, high sawing efficiency, and simple peripheral circuits, providing a complete solution.
High branch saw program performance characteristics:
> Built-in 12-bit ADC, multi-channel operational amplifier, PGA, N+N drive, simplifying the peripheral circuit
> Optimized sensorless startup algorithm, 100% startup success
> AD comparator linkage mechanism, lower operating speed, more accurate high-speed commutation, and higher efficiency
> Continuous output of large torque at low speed, the maximum torque can be maintained continuously when the rotor is locked
> With input over-voltage and under-voltage protection, over-current protection, over-temperature protection, phase-to-phase short-circuit protection, phase loss protection, locked-rotor protection and other protection functions
> Meet IEC60730 CLASS B standard
