Q:What's the capacitor on the power tools?: Start the motor. Hand to turn and start, then you can judge the capacitance is not enough or invalid.

Q:Can adjustable speed power tools use direct current?: The other is a rechargeable battery, which is powered by a low voltage direct current battery,

Q:Why use helical gears for power tools?: Good meshing performance. In the line of contact of helical gear teeth for line tilt and the axis of gear, gear engagement and disengagement began to be gradual, and stable transmission, low noise, and the meshing method also reduces the influence of manufacturing errors on transmission.

Q:How to connect the sleeve head and the power tool?: The sleeve head is normally used for an electric wrench, and the electric wrench is connected with a common hole of the sleeve head, and the socket head of different sizes can be changed at any time.

Q:The insulation resistance of two kinds of hand-held power tools is not less than: Insulation resistance is the most basic insulation index of electrical equipment and electrical circuit. For the handover test of low voltage electrical equipment, the insulation resistance of the motor, the distribution equipment and the distribution line shall not be lower than 0.5M at ambient temperature (for the running equipment and circuit, the insulation resistance shall not be lower than 1M /kV).

Q:Hitachi electric tool charger 10.8V/12V working principle: Because Hitachi has mature technology in lithium battery technology, so Hitachi's lithium-ion batteries with overload protection, control technology unique overheating protection and current protection, the battery core is independent monitoring.

Q:What is the torque requirement of a household electric tool motor?: Because I want to choose a high-end motor, with electric tools, electric motor is very expensive, at least have to more than 2000, good 50 thousand, but little noise, asked the motor manufacturers, he said that when the actual work is it has a torsion index, because the power is not the way to quota, but is the torque it can be. For example, how large saw blades can carry saws, and how long and thick wood can be sawed. However, this kind of motor is generally not used by woodworking, and is mostly used by precision equipment. I can't just try to play with such expensive things.

Q:What's the function of the capacitor in the power tools?: It acts as a phase shifter, because power tools are generally single-phase alternating current. Motor single-phase can not start operation, if you add a capacitor, you can play the role of starting and running. The capacitor turns a single-phase alternating current into a two phase alternating current

Q:Can I bring power tools for the subway?: You can bring power tools on the subwayIt is strictly prohibited to carry inflammable, explosive, toxic, corrosive nature, and destruction and other dangerous goods (such as detonators, explosives, fireworks, gasoline, diesel, kerosene, paint, calcium carbide, liquefied gas, various acids etc.) and easily defaced subway train and station equipment and environmental articles.

Q:What power tools are better for sawing wood?: Most important, the key is the tool is good. Second. You should see saw thick wood, and now you, what are the requirements for electric tools to saw straight, straight, not those who saw me. What did not say, cutting machine, electric circular saw, is the best on the cloudsUsually use wood knife because the wood fiber of this material is a kind of tool grinding angle grinders can only be used in some places mainly rely on the wood carving knife
