Hey guys,
Recently I removed a motor from an Oral B Braun toothbrush, simply because the gears it had for oscillation were already set up and in a nice little housing. It was powered by a 2800mAh rechargeable battery.
Now my problem is I can't seem to power it to produce results like it did with the battery. What I've tried so far:
- I've noticed any DC supply with an output of over 1A results in the motor "chugging" regardless of the voltage being 5 or 12
- A DC supply with 1A and 6V output has seemed to work best so far...it managed to supply almost the same amount of torque although the DC supply did burn out..
- A DC supply with 700mA gets the motor going with good speed..but no torque..
A note worth mentioning...these are all old DC supplies I have found from old devices which I have just cut the ends of and soldered directly to the motors contacts..maybe thats where I'm going wrong.
To summarize, how would I go about finding the optimum voltage/current for this motor (I have tried searching for its spec sheet, no luck)
Thank you in advance guys!
Regards,
Max
