Hello guys, i have a got a problem with my Beard Trimmer's motor....
The trimmer stopped working while i was trimming.... So i have dismantled and checked for the problem and found out that it was due to motor failure. The motor in the above picture is the one i am talking about, a DC motor of rating 1.2 Volts

Now i need to replace the motor but the problem is that for this motor to run the trimmer it requires a shaft attached to the axle as marked in the above figure. Can anyone what do we call such stuff which are attached to the motors axle (in case of toy cars we have some gears attached).

will a motor be available with such a shaft attached to it or do we need to fix it separately...


If we can get such a motor with the shaft already attached, where can we get it?
If we need to fix them separately, where can we obtain such shafts..
Its urgent, please reply soon..

An offset shaft or irregular axle shape used to change rotary motion into linear is often called a cam.

Best bet is to a search on the internet for parts for your brand and model of beard trimmer. If they sell a replacement motor, it is likely that the cam will be included.

Here's a simple, reliable, inexpensive, three-word solution: Use scissors instead.

yes, exactly as u said it i used to change rotatory motion into linear..
thank you for letting me know the technical name of it.

even i thought of using them but the the cam and the axle look like a made out of single mold...
even if they are not made of same mold they are very tightly bound to separate..

From my experience with that kind of machine, the problem is more likely with dirt upon electrical contact in the switch or other part, not with the motor.

i have checked the complete circuit of the trimmer for continuity, improper terminals and regarding the battery.
everything is fine, even the switching between on and off is also proper.

well, thanks to all those who responded to my query..

the actual problem lies with the motor itself.. i have opened the motor and found out that the the commutators which slide past the brushes of the motor are not making proper contact with the brushes. This is because the brushes got bent in an irregular fashion and hence are out of contact with the commutator. I have set them right are the motor is functional now.

Good for you.

I commend you too we live in such a throw away society nowadays it's nice to hear of someone repairing somthing instead of tossing it and buying new.
