An electric drill is an indispensable tool in the arsenal of any craftsman, be it an experienced carpenter or a novice repairman. But what to do if suddenly this assistant refuses to rotate? Concern, of course, arises immediately. I don’t want to stop work, what if there’s an urgent repair? Don't lose your head! Reasons whyelectric drillmay not work, quite a few, and most of them can be fixed on your own. Let's look at the most common problems and ways to solve them.
The main reasons why an electric drill may not rotate
Power problems
Let's start with the most obvious. Ifelectric drilldoes not receive power, it, of course, will not rotate. Check a few things:
- Socket. The simplest, but often overlooked point. Make sure the outlet is working and connected to the mains. You can check by connecting another electrical appliance to it.
- Power cord. Inspect the wire for damage - cracks, kinks, exposed areas. A faulty wire is a serious danger; it is better not to take risks. If the wire is damaged, it must be replaced.
- Power switch. Manyelectric drillshave a built-in power switch. Make sure it's turned on.
Do you remember if there were any power surges in the network? Sometimes, short-term voltage fluctuations can cause electronics to fail, although this does not happen often. In such cases, more serious diagnostics may be required.
Engine problems
If the power is fine, then the problem is most likely in the engine. Here are some possible problems:
- Commutator brush wear. Brushed motors use brushes that wear out over time. Worn brushes do not make good contact with the commutator, resulting in reduced power and ultimately engine shutdown. Replacing brushes is a relatively simple procedure that you can do yourself. (For example, for some drill models you can find video instructions on YouTube).
- Engine clogged with dust and chips. Regularly clean the engine of dust and chips, especially if you frequently work with hard materials. This will help avoid overheating and extend the life of the engine.
- Motor winding failure. This is a more serious problem that requires professional repair or engine replacement. Symptoms include a burning smell, sparking and lack of rotation.
Gearbox problems
A gearbox is a mechanism that transmits rotation from the engine to the chuck. If there are problems with the gearbox, thenelectric drillwon't rotate either:
- Wear of gear teeth. Over time, the gear teeth in the gearbox wear out, reducing transmission efficiency and eventually stopping rotation.
- Gearbox clogged with chips. Chips may become stuck in the gearbox, blocking rotation. It is necessary to disassemble the gearbox and clean it.
- Damage to the gearbox seal. A damaged oil seal can lead to lubricant leakage and gearbox failure.
Problems with the cartridge
The chuck is designed for fixing drills. If the cartridge is jammed or broken, thenelectric drillwill not be able to rotate.
- Drill bit too tight. Make sure the drill bit is clamped tight enough, but not too tight to damage the drill bit or chuck.
- The cartridge is jammed. If the chuck is stuck, try gently rocking it or using a special chuck wrench.
- Cartridge damaged. If the cartridge is broken, it must be replaced.
What to do if the electric drill does not rotate? Step-by-step troubleshooting instructions
- Power check. Start by checking the power supply - outlet, wire, switch.
- Inspectionelectric drillsfor damage. Inspectelectric drillfor cracks, kinks, exposed wire sections and other damage.
- Cleaningelectric drillsfrom dust and chips. Clearelectric drillfrom dust and shavings.
- Checking the condition of the commutator brushes. Check the condition of the commutator brushes and replace them if necessary.
- Checking the gearbox condition. Check the condition of the gearbox for wear on the gear teeth, clogging with chips and damage to the seal.
- Checking the condition of the cartridge. Check the condition of the cartridge for jamming and damage.
Prevention of breakdownselectric drills
To avoid breakdownselectric drills, it is recommended to follow the following rules:
- Clean regularlyelectric drillfrom dust and shavings.
- Monitor the condition of the commutator brushes and replace them promptly.
- Don't overloadelectric drill.
- Use quality drill bits.
- Storeelectric drillin a dry place.
I hope this information will help you understand the reason why yourelectric drilldoes not rotate. And remember, if you are not confident in your abilities, it is better to turn to a professional master. Health and safety always come first!
