FAQ

Is the motor of an electric tool the alternating current motor or the direct current motor?
The series motor is usually used. The series motor is connected in series because the stator and rotor windings are connected together, so when the current is reversed, the magnetic field is reversed, so the torque direction remains the same. However, according to this principle, the motor works at 180 degrees after the torque is gone, so even the AC motor, but also need to reverse, in order to work like a DC motor.The rectifier also needs to be rectified if it is operated under the direct current. The rectifier bridge is very small. On the circuit board, there are four diodes close together, mostly rectifier bridge
What kind of material does the power tool case have?
An electric tool case is made of a variety of materials, such as plastics, cast iron, etc..
What are power tools?
Electric tools divided into many categories: hammer drilling, grinding, sawing, cutting, assembling, charging, cutting and so on, each class has a lot of varieties.
Is BOSCH's power tools good or MAKITA's power tools?
MAKITA electric tool features:The utility model has the advantages of small noise, strong power, good performance, long service life, light body, strong and durable, easy operation and convenient repair. The utility model is the necessary high-quality product for professional personnel or amateur DIY personnel.
How are hand powered tools classified into class I, class II, class III?
Nowadays, class I hand held power tools are virtually discontinued. The class II hand-held electric tools are widely used. Class II hand held electric tools are generally used on special occasions such as wet environments, metal containers, etc..
What is the working principle of power tools?
AC motor, AC motor of induction motor, its strong induction current (eddy current) magnetic field generated in the rotation of the magnetic force on the rotor copper bar, continuous cutting, according to Lenz's law, the induced current has the effect of relative motion occurs against the rotor magnetic field and the rotor is, with the magnetic field and rotation. But the rotor rotation speed of the high speed magnetic field does not transform, otherwise it will not be able to cut the copper lines.
How are the I, II, and III classes of power tools classified?
The popular point is that:The 1 type of tool is metal housing with ground wire.The 2 type of tool is the insulated housing.The 3 type is low voltageOfficial point of explanation can be searched for power tool category ~!
Why hand grinding sand turbine, electric drill, impact drill and other power tools plug is two, plug is not three plug
In recent years, leakage protection performance and the reliability greatly, has become a standard power supply, reliability of human protection over ground protection to a certain extent, but the impact of grounding protection and leakage protection to human body protection, so many hand-held electric tools to cancel the earthing protection, relying instead on leakage protector. And use the two eye plug.Look at the instructions for the hand-held power tools with two plugs. All require that the power supply be equipped with an electric leakage protector.
