Q: What are the commonly used rotor types for power tools?: Concrete vibrator: concrete used for pouring concrete foundations and reinforced concrete members to eliminate porosity and increase strength. The high-frequency disturbing power of the electric direct acting vibrator is driven by an electric motor to rotate the eccentric block, and the motor is powered by an 150Hz or 200Hz intermediate frequency power supply.The planer: used for planing wood or wood structure, mounted on the bench can be used as a small bench plane. The planer cutter shaft by the motor shaft through the belt drive.

Q: What kind of power tools are hand drills? 1, 2 or 3?: You can see the cable plug, the aluminum shell is inserted three I tools, is grounded, the aluminum shell and some II tools, because it has a plastic insulation between the stator and the aluminum shell, so it is the installation of two wire plug.

Q: How about plug wires and cables for power tools?: Class II tools, that is, insulated structures, all double insulated power tools. The specified voltage is over 50V, and the grounding device is not allowed in class II tools. Generally insulated enclosures. Generally speaking, the design of II tools made use of personal protective equipment operator to some reliable method in the tool, the tool has a double protective current, guarantee in the fault state, when the basic insulation failure, insulation and reinforced insulation provided by additional electric shock protection.

Q: What's the role of carbon brushes in electric tools?: Changing the direction of the current (in the commutator motor brush, also plays a role reversal)
