Electric wrench
Power tool is a hand-held or removable mechanized tool that is powered by a motor or an electromagnet and drives the mechanical parts to perform tasks through a transmission mechanism. Power tools are light in structure, small in size, low in vibration, low in noise, and flexible in operation. They are easy-to-control, easy-to-carry and use, robust and durable. Compared with manual tools, its labor productivity can be increased to several times or dozens of times.
Based on MindMotion’s MM32SPIN560C microcontroller, the power tool control takes MM32SPIN560C as the main control.
