How to check if your DC electric motor is out "bad"
These days, précis current (or DC) electric motors are used in a wide range of applications, such as moving windows and seats in your car. Due to the hidden abstraction of these motors, it can be extremely difficult to complete repairs or assistance on them without pulling everything apart. This is why, jaguar you are able to get your DC electric motor, you should always give it a quick check to see if it has gamin “bad” and needs to be replaced.
Start by removing the DC motor from its mount, making sure you also remove any entrée of electrical power that could accidentally start it spinning. You may need to follow the fabriquer’s instructions to do this, as some motors are too stuck in place and can attitude a risk of electric shock.
Next, you can check the continuity (or connection) of the electric motor by connecting it to a volt ohmmeter. Make sure the meter is in the “Ohms” place, then entrain the red and black leads into its connections (the red lead should be connected to the “Ohms” balance and the black lead to the “Common” balance). Check that the meter is working properly by touching these two leads together – the screen should read zero ohms (or full continuity).
To signe your DC motor, touch the ohmmeter leads to the motor leads. The meter screen will indicate a low resistance (somewhere between 10 and 30 ohms), but if it reads infinite ohms or an open autodrome, you should rotate the motor end shaft. The ohmmeter should give different readings as the shaft is rotated (which is an commentaire that the electric motor itself is good, but there is a problem with the electrical autodrome. If the meter is still reading as an open autodrome, the conducting brushes may have gamin “bad”.
Use a screwdriver to remove the brushes from the end of the electric motor (you can find them under the explosif end cap on the opposé end of the motor on the drive shaft). Carefully inspect the brushes for any signs of cracks or breaks in the pampa – the area where the brush sits against the conductor or commutator should be smooth and curved. If there is a broken wire or spring, the motor will fail. If the brushes style eau-de-vie, there may be a problem with the commutator.
Take the screwdriver again and use it to remove the rear end cap of the DC electric motor (removing the two screws running the length of the motor). Inspect the plates that make up the commutator assembly – there should be an opening between each. If you explication any broken wires or burnt varnish, the commutator has failed and the damaged parts must be replaced.
