Q:What's the role of carbon brushes in electric tools?

In addition to induction type AC asynchronous motors, there is no outside. Other motors are provided, as long as the rotor has a reversing ring.The principle of electric power generation is that a magnetic field cuts a wire to produce an electric current in the wire. The generator cuts the wires by rotating the magnetic field. A rotating magnetic field is a rotor, and the wire to be cut is a stator.

Q:What material does the power tool housing fit?

Electric drill: the main specifications are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49mm and so on. The figures refer to the steel whose tensile strength is 390N/mmThe maximum diameter of a drill drilled on a material. 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. An electric screwdriver adopts a clutch, a transmission mechanism, or a gear drive mechanismThere are M1, M2, M3, M4, M6 and so on.

Q:How about plug wires and cables for power tools?

Class I tools are common type power tools with a rated voltage of over 50 volts. Class I tools not only rely on basic insulation but also include an additional safety measure in the protection against electric shock. The method is that the accessible conductive parts and protection has been installed in the fixed line in the (ground) wire together, make accessible conductive parts in the basic insulation does not become damaged in the charged body. Plug for three pin plug type tool.

Q:What's the name of an electric tool for riveting screws into wood? Not understand!

If the factory is assembled, use an electric screwdriver! Only suitable for twisting small screws! Because the torque itself is not large! Like you twist it on a wood, use a Zigong drill, or a rechargeable drill! Because of these two belts with adjustable torque! Unlike an electric drill, it always turns that way! This torque is automatically separated by reaching a certain torque! If you screw a big screw, it's an electric wrench!

Q:How are the I, II, and III classes of power tools classified?

Class I. In addition to basic insulation, the device has an additional safety measure. There is no grounding terminal on the shell of class I equipment, but there is a grounding terminal inside, and the power cord with protective plug is drawn out from the equipment.Class ii. The device has dual insulation and insulation protection measures.Class III. The device relies on extremely low safety voltages to protect against electrical shocks.

Q:Which is good between pneumatic tools and power tools?

Pneumatic tools are the mainstream trend, pneumatic tools more suitable for long time work, rather than power tools, permanent fever, and even burned out the internal parts, pneumatic tools can be seen more secure. Power tools initial investment is low, but long-term use of energy consumption is higher, and tool maintenance and replacement costs are higher, and pneumatic tools more environmentally friendly, long-term use cost is much lower than the electric.

Q:Compared to pneumatic tools, what are the advantages of electric tools?

At the same time, reversing operation, pneumatic tools, small size, high speed rotary speed, easy to adjust, no danger of fire, the air compressor can also be used in the house, is the best choice for sheet metal, paint, furniture manufacturing, auto hub processing, etc..

Q:Is the motor of an electric tool the alternating current motor or the direct current motor?

To be exact, they are generally series motors, so they are alternating current motors. The direct current motor is usually used as charging tool and driven by DC motor. Also useful for three-phase motors, such as concrete vibrators, are three-phase motors.If it is DC power supply, must have rectifier power ah, because the power supply is 220V AC, must be rectified into DC to use.

Q:What kind of material does the power tool case have?

In 1895, the German overtone produced the world's first direct current drill. The outer shell is made of cast iron and can drill holes in the steel plate 4mm. Then there was a three-phase power frequency (50Hz) electric drill, but the motor speed failed to break through the 3000r/min. In 1914, there was a single-phase electric motor driven by a series of exciting motors, and the motor speed was over 10000r/min. In 1927, the power supply frequency of intermediate frequency electric tool 150~200Hz, it not only has the advantages of high speed single-phase series motor, and has the advantages of simple structure, reliable three-phase motor, but because the need if current supply is limited.
