I have a circulating pump motor with a 3.5mf 280vac cap that is bad. Can I replace it with a 3mf 250vac cap without having problems?

If you have this Desoldering Gun Station there is something you should be aware of the two screws that hold the motor to mounting for pump can come loose and make raddling noise
One note this unit has been repaired already once because of switching power supply regulator ic chip failure
Now this with the vacuum motor mounting issue yes I give this Desoldering station a very hard work out and use about every weekend to do some type of project
The fix is taking the vacuum pump assembly out and take the metal cover off and you will see the two screws on it

Hi,
i am asking for some Help.
I have one of these Nescafe Aeroccino (Milk Frother) things with a bad motor.
The Motor didn´t start anymore and internet is full of users just swapping the motor for a Mabuchi RF-500TB-12560.
So i got a few of these from Banggood.
I swapped the motor and now i have a new fault condition.
In a working Frother you would press the start button, it will light red and work for a few minutes.
If you press longer it will light blue and just mixup the milk.
With the new Motor it just starts... -

trying to fix Philips toothbrush 4100 (HX369BK)
The battery started draining quickly.
After disassembling it, I discovered that the motor gets very hot when brush is off, which is apparently causing the battery to lose charge.
The motor is connected to contacts M1 and M2.
When I turn on the brush, 0.4V appears on these contacts, and the motor starts running as expected.
But when I turn off the brush, the voltage changes to 3.8V—exactly the same as the battery.
The motor gets so hot you can't touch it. And after 5 minutes, the battery drains to 0V.

Hi all forum members,
Found this unknown motor discarded in a junk yard and took home for learning experience. By the look of it, I suspect it is taken out from a type of air blower probably running on ac power. I used digital multimeter on ohm/resistance scale and it doesn't read anything on those 2 black wires. So, this motor is not shorted and should be good to run.
Correct me if i am wrong on the initial test.
Can anyone kindly advice on how to test run this motor based on visible external two black wires. Fyi, i don't see any marking on the motor body nor smell anything...
