Q: How are hand powered tools classified into class I, class II, class III?: Class I protection against shock of the product depends not only on the basic insulation of the equipment, but also on additional safety precautions. The method is to connect the electrically conductive parts that may be touched with the protective wires in the installed stationary lines so that the accessible, electrically conductive parts are not electrified in the event of basic insulation damage. Such products are: hand-held power tools, mobile daily appliances, mobile mechanical and electrical equipment.

Q: What are the commonly used rotor types for power tools?: Electric tools commonly used bearing type: 606, 607, 608, 626, 627, 628, 629, 6000, 6001, 6003, 6004, 6200, 6201, 6202, 6203, 6303, 61907, 688 commonly used carbon brush models: 50#, 408#, 43#, 44#, 303#, 21#, 6M etc.

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'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: What is the working principle of power tools?: A direct current motor called a direct current motor. Due to the magnetic field circuit and armature circuit of the different links, can be divided into series motor, motor, compound motor;

Q: Power tools are power tools?: Now, that's pretty much the case. Now most power tools are powered by electricity. However, some of them are pneumatic, especially the environment where no electrical work is required. This should be equipped with an air pump externally.Small, of course.

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: What are power tools?: Profile cutting machine, Bo Hai Power Tools Co., Ltd. is a research and development, production and sales of Bo Sea series of power tools specialized manufacturers. In order to ensure product quality and standards, the company continuously improve the quality of employees, and the introduction of automatic production equipment and strict inspection.

Main products: electric drill, impact drill, electric hammer, electric drill, wireless, reciprocating saws, electric scissors, angle grinder, straight grinder, die grinders, sanding machine, blow... Last modification date: 2006-07-243. impact drill

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.
