Q:How are hand powered tools classified into class I, class II, class III?
Simple methods are: hand-held electric tools for metal shell for class I. The plastic case is of the type ii. Class III uses safe voltage.
Q: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.
Q:Is there an electric tool for screwing bolts? It's bolts, not screws?
The 2 floor is good! Electric wrenches, pneumatic wrenches, front with prominent slot, you can clamp different sleeve, find the corresponding sleeve with buckle...
Q:What is the working principle of power tools?
An electric motor that rotates by alternating current is called an alternating current motor. There are many kinds, mainly:A, the series excitation motor - rectifier DC generator for AC motor, namely into this kind of motor, at the same time shift due to alternating current in the magnetic field and the armature circuit, therefore, the direction of the torque constant remains unchanged, the machine is kept turning. This kind of motor can also be used as AC and DC, so it is also called universal motor". Vacuum cleaner, sewing machine and other household appliances, etc..B, an induction motor -- a device that rotates the rotor in the rotating magnetic field and causes the rotor to rotate due to the action of eddy currents. Rotating magnetic field is not caused by mechanical method, but by alternating electric flux in the number of electromagnets, so that the magnetic properties of the cycle of change, can be seen as a rotating magnetic field. Usually three-phase induction motor (with three pairs of magnetic poles) is used. The motion of the DC motor is just the opposite of the direct current generator. In the generator, the induced current is formed by the induced electromotive force, so they are in the same direction. In an electric motor, the current is supplied by an external power supply, and the direction of the induced electromotive force is in opposition to the armature current I.C and synchronous motor - the motor with the armature from one pole to the second pole, just the same as the current that turns into the current. This kind of motor cannot start on its own and must be operated by another motor or special auxiliary winding so that the proper frequency can be reached before it can be switched on. If the load changes and the speed changes, the speed is not in line with the AC frequency, so that the pace of disturbance, tend to stop or cause damage. Due to restrictions, it is not widely used.
Q:Power tools are power tools?
Divided into electric, pneumatic, gasoline tools, currently on the market these 3 main types. I've been a tool for over 10 years
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:Why hand grinding sand turbine, electric drill, impact drill and other power tools plug is two, plug is not three plug
Each of these devices has a "back" logo indicating double insulation protection, and the double insulated layer forms insulation protection between the outer shell and the inner part of the tool, thereby preventing the occurrence of electric shock. So no three plug in,
Q:How are the I, II, and III classes of power tools classified?
In accordance with the electric shock protection methods, electrical equipment is divided into the following 4 categories:0 category. The device relies solely on basic insulation to prevent electric shocks. There are no ground terminals on the live conductors of the 0 types of equipment.
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:Is the motor of an electric tool the alternating current motor or the direct current motor?
Compared to the AC motor and DC motor, because there is no commutator (see DC motor commutation), therefore has the advantages of simple structure, convenient manufacture, relatively strong, easy to make high speed motor, high voltage, high current, large capacity. The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts.
We are a manufacture specialized in rechargeable power tools, such as electric blower,fitness equipment ,etc.Besides,we are incessant imploding the new products for our clients and market. We are holding the certification for "GS" "CE" "EMS" "CSA" etc. Also,it is in the process with ISO9000.
