The hammer drill works intermittently
To make sure that the hammer drill really needs to have its electric motor brushes replaced, you will need to measure their length. If the brush length is less than 8 mm, then the parts need to be replaced. Moreover, they need to be replaced in pairs, since they also wear out evenly. How are the brushes replaced on the hammer drill? To do this, you need to remove the devices from the brush assembly, and then disconnect the power wires from the terminals. Instead of worn brushes, you need to install parts of a similar design.

The perforator is checked for proper operation - after installing new brushes, the tool will work clearly, without interruptions and sparking. Only minor sparking is allowed, so after replacement, make sure that the power tool is working properly.

Malfunction of the electric motor of the hammer drill
Everyone knows why an electric motor is installed in a hammer drill oman telegram data without the need for a description. However, a collector electric motor, which consists of an anchor and a stator, can also fail over time. To identify a breakdown of the electric motor, it is necessary to perform a number of certain manipulations that allow you to repair or replace the electric motor. How to check the serviceability of the rotor and stator of the electric motor of the hammer drill, we will find out below.

Checking the serviceability of the anchor or rotor - first, a visual inspection of the collector plates is carried out. The presence of carbon deposits on the copper plates is unacceptable, and if such signs are present, they must be eliminated. Next, using a multimeter, you need to check the serviceability of the rotor winding. To do this, first set the multimeter to the resistance test mode, and then touch the steel core with one probe, and check each collector plate in turn with the second.
