SEARS POWER TOOL PARTS HOW TO

So, a 14 gauge cord is larger (thicker) than a 16 gauge cord, because the diameter of the 14 gauge cord is larger than the diameter of the 16 gauge cord. As the gauge number goes down the diamter of the wire goes up and cords become larger ( thicker). As the gauge number goes up the diameter of the wire goes down and cords become smaller ( thinner). ' Gauge' is short for American Wire Gauge (AWG), and is a system of measuring the diameter of cord or bundle of electrical wires. Most power tool cords are between 12 and 18 gauge, but the most common is 16 gauge. 3-wire cords end in three-pronged outlet plugs and also come in a variety of gauges. The third wire of the cord is a ground wire that directs any extra charge in the power tool away from the tool and away from the user. 3-wire power cords also protect tool users from shock. They end in two-pronged plugs and come in a variety of gauges. 2-wire power cords protect the tool user from electrical shock with a system of double insulation. First, power cords come in two designs for most power tools: 2-wire and 3-wire. Power Cords There's a lot lot to know about power cords that can help prevent damage to a power tool and the cord itself.

Below is some extra information on each major electric power tool part already described above, when and why they break down, and how to troubleshoot tool failure early. Each repair comes with its own pointers and guidelines, but this basic understanding of how electric tools work is a good foundation to start from. That's enough technical understanding for most tool users to be able to diagnose and fix most of the common problems that power tools run into. From the motor assembly, the physical energy created by the motor is transferred to the tool's motor shaft and applied to the tool's work. They work together to create physical energy with the electrical energy from the tool's power source.Д¦. Together, the armature and the field make up the motor assembly. The field is an assembly unit that is ring-like and fits around the armature. The armature is an assembly unit, is shaft-like, and fits through the field. The armature is one major half of the electric motor. The precise place where carbon brushes touch the armature is called the commutator.ДҐ. The part of the motor where the brushes make contact is called the Armature. Carbon brushes carry electricity to the electric motor by making direct contact to the motor itself. These ' brushes' are small pieces of carbon that are important contact points between the tool's power source and the actual electric motor in the tool itself.Д¤. The electricity in an electric power tool has a few more important points of contact before it is changed in the tool's electric motor.ДЄfter leaving the power switch, the electricity from the tool's power source passes through the tool's Carbon Brushes. When the switch is in the ' on' position, the circuit is completed and the electrical energy can continue past the switch an into the tool's electric motor, putting the tool in operation.ДЈ. When the switch is in the ' off' position the electricity can't go any farther because the elctrical circuit is not complete, putting the power tool at rest. The electricity continues along the wires inside the cord's insulation until it reaches where the wires connnect to the tool's Power Switch. The electrical energy enters the tool's Power Cord.Дў. Below is a short description of what happens to electrical energy inside an electric power tool and the key places inside a power tool to look for wear or damage:ДЎ. This is because electrically powered tools all use the same principles in their electric motors to make physical energy out of electrical energy. The Basic Parts of Electric Power Tools There are many tool parts common to electric power tools. Even some of the repairs and maintenance required for electric power tools are fast and easy to do. If the problem can be pinned down early, then the tool is just a part and a quick repair away from being almost like new again. And understanding what goes on inside of a power tool makes diagnosing problems easier. for most power tools, and happens to be where most maintenance is required Although there is a lot more to be said about how electric motors work, no one has to be an electrical engineer to understand a motor's basic parts. The process of making physical energy with electrical energy is very similar and where most performance issues occur. The physical energy created by the motor is then applied to the tool's work.ДЄctually, what makes most electric power tools ' different' from one another depends on how the physical energy is used, or its application. This electricity is converted by a tool's electric motor into physical energy. Each power tool receives electrical energy from an outlet or battery.
