Hi, I have just got superannuated after 33 years of work in the IT and Telecom industries. Now with sufficient time on hand, I intend to engage myself seriously in my hobbies. I have been with 'Instructables' for quite some time and I find this to be one of the best DIY sites. I enjoy going through all the projects sent in by the members. Cheers!!

    Thanks Stan,I will remember your guidance for sure. Using PVC piping as an outer casing for the motor is a brilliant idea. That will rule away shock hazard.I desperately need a motorized polisher and a grinder. Lets see how to go about it.

    This is a wonderful polishing tool, with only a few components. I have one unused hand mixer with a 230 VAC motor. I wonder if I extract the motor and mount it likewise. Unfortunately your kind of polishing jib is unavailable here, so I suppose I will have to make that also. Thanks for sharing.

    Oh Wow Stan, never thought of salvaging the motor from an electric toothbrush, although I have been using one for years now. Very useful tip, especially as one can make a variety of things with these small motors.Is the motor even that big.?! I always thought that there was some sort of a vibrator inside. I am posting here a picture of my toothbrush. Mine runs on a single AAThanks for sharing this.

    repairing a small DC electric motor

    many thanks for your prompt response.Yes friend, I also was getting the same opinion about the power input getting erratic. I shall dissemble the motor and feed it 12V DC from one of the eliminators. Hope that works. Also will see the output being given out by the speed control board.The speed control board/ PCB has a small Pot, some resistors and a three legged regulator. Could it be that the bushes are loose and are only touching the commutator intermittantly?I will take a photo and send you shortly.

    repairing a small DC electric motor

    Hi,Around a year ago, I purchased an electric hand drill/ mini dreme along with accessories for cutting, drilling, polishing etc. This was purchased from an online Hongkong shop. This drill worked very well to begin with, but now I find that the motor runs haltingly. I dissembled the unit and found that the 18 V DC power is fed to a voltage stabilizing circuit and a small potentiometer for speed control. I tried oiling the motor, but the motor only runs haltingly. I did not find the clips on the rear of this motor, so I could not dissemble it. Can you please diagnose the problem and whether this can be repaired.To give you a better idea, I am giving a video link to the faulty motor in operation.https://youtu.be/xcwTVZWtN9oMany Thanks,Atanu
