What is the performance of power tools and how is life tested?
The load shall be automatically controlled by a feedback loop or controlled manually. In the testing phase, the torque, PRM and input / output power, constant current, constant torque, constant speed and other load signals should be displayed and recorded in real time. Test the power tools until they are completely scrapped, and analyze the reasons based on historical data. Most importantly, you must control and test multiple UUT at the same time, without affecting each other.
In the life test of power tools, periodic loading of single power tools is required, and electrical tools are tested for 48 to 72 hours at different load stages.
