Malfunctions of the electric motor of the hammer drill

[shapanwwuom]

The heart of any power tool is a collector electric motor that converts electrical energy into mechanical energy. If all the diagnostic and repair steps described above have been completed, but the hammer drill does not work, then the hammer drill electric motor needs to be repaired. This is one of the most complex elements of the tool that requires a special approach. Breakdowns of this unit can be divided into two parts - faults in the rotor and stator.

If the anchor of the electric motor is broken, diagnostics and repair
You need to start diagnosing the rotor (anchor) by checking the condition of the collector - these are the plates or lamellas through which current flows through the brushes.First, you need to inspect the condition of these lamellas, which should not have signs of carbon deposits or blackening. If there is carbon deposits, then it is possible that the reason for the failure is in it. It is recommended to clean the carbon deposits with the finest paper sandpaper. For a control cleaning, you need to take cotton wool with alcohol and thoroughly clean each plate.



After cleaning the collector and replacing the brushes, you need canada telegram data to check whether the hammer drill works or not. If such a hammer drill repair does not give positive results, then you will need to arm yourself with a multimeter and check the suitability of the anchor.

The reasons for the breakage of the anchor of the power tool are:

Damage to the winding insulation, which leads to an increase in resistance
Winding integrity failure or breakage
Delamination of the steel core
The process of checking the serviceability of the motor anchor consists of the following steps:

Using a multimeter, measure the resistance of the armature by touching one probe to each plate of the collector in turn, and the second to the core.If the device does not show anything, it means that the winding insulation on the steel core body is not damaged. If the device shows a value on any plate, it means that the rotor needs to be rewound.
