FAQ

What's the role of carbon brushes in electric tools?
Carbon brush specific function1. the external current (excitation current) is added to the rotor by carbon brush (input current);2., the static charge on the big shaft is introduced into the earth (carbon brush) through the carbon brush (output current);3. lead the main shaft (ground) to the protection device for rotor ground protection and measure the positive and negative voltage of the rotor;
How about plug wires and cables for power tools?
Class II tools must be made of an insulated power plug, and the power plug is joined to a soft cable or cord to form a non renewable power plug. Class II tools only allow the use of non - renewable two pin power plug. The II class tools are marked with "back"". Class III tools, that is, secure voltage tools. Its rated voltage is not more than 50V, and the protection against electric shock depends on the power supplied by the safety voltage and no voltage higher than the safety voltage in the tool.

What are the common rotors of power tools?
Electric drill: the main specifications are 4, 6, 8, 10, 16, 19, 23, 25, 32, 38, 13, 49mm and so on. Figures refer to the maximum diameter of the drill drilled on the steel whose tensile strength is 390N/mm. For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.Electric grinding machine: a tool for grinding with a grinding wheel or millstone. A vertical electric wheel and electric angle grinder.Electric wrench and electric screwdriver: used for loading and unloading threaded fittings. The driving mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. Specifications are M8, M12, M16, M20, M24, M30 and so on. The electric screwdriver adopts the embedded clutch, transmission mechanism or gear drive mechanism. The specifications include M1, M2, M3, M4, M6 and so on.
