Q&A
Q:Does our product support customization?
A:Our products can support customization, but there are requirements for the quantity, you can contact us for details.

Q:When you call or send a quotation request, what information do you need to provide?
A:Your needs for the product, and what you want to know in detail.

Q: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

Q:What's the role of carbon brushes in electric tools?: Carbon brush specific function1. the external current (excitation current) is added to the rotor by carbon brush (input current);2., the static charge on the big shaft is introduced into the earth (carbon brush) through the carbon brush (output current);3. lead the main shaft (ground) to the protection device for rotor ground protection and measure the positive and negative voltage of the rotor;

Q:What devices must be available for all hand held electric tools?: Anti leakage, splash prevention, anti movement, anti overheating

Q:What safety problems should we pay attention to when using electric drills or hand-held power tools?: All conducting parts must be well insulated,

Q:What's the name of an electric tool for riveting screws into wood? Not understand!: An electric drill can be used! But it can't adjust the torque! There are four types of professional screw twisting tools!

Q:How to detect the rotor of power tools?: Rotor spark. 1) the carbon brush and commutator rotor, no free contact. 2) the connection spring on the carbon brush nest is burned, and the person who is burned is not able to connect normally. A vicious circle, sparks plus sparks. Machine failure will also occur.

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: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:What kind of power tools are hand drills? 1, 2 or 3?: I class: in the prevention of electric shock protection, in addition to relying on basic insulation, but also the need for zero protection.Class II: the tool itself has double insulation or insulation without the need to protect the ground.Class III: Powered by a secure, ultra low voltage power supply, no voltage higher than the safety supply voltage is generated within the tool.The above is the classification of insulation categories.

Q:What are the commonly used rotor types for power tools?: Power tools are mainly divided into metal cutting, power tools, grinding power tools, assembly of power tools and railway power tools. Common electric tools electric drill, electric grinder, electric wrench and electric screwdriver and hammer, impact drill, concrete vibrator, planer. Accessories for each power tool: rotor, stator, gear, bearing, switch, carbon brush, carbon brush holder, carbon brush cover, power cord. Go down and stop repeating.
