Re: Do these motor brushes need replaced?
Well there looks to be plenty of them left, so I would say no. -

Re: Do these motor brushes need replaced?
The rotor is hard to turn with the brushes removed? The brush still have a log way to go.
The motor bearings still have any lubricants?Never stop learning

Re: Do these motor brushes need replaced?
I can't tell whether the bearings still have lubricant
And the rotor is still hard to turn even with the brushes installed,Last edited by ncovert; 07-12-2012, 05:08 PM.Comment

Re: Do these motor brushes need replaced?
Either it uses the bushing or bearings, sounds like they are in bad shape.

Re: Do these motor brushes need replaced?
Can you easily turn the rotor since the rotor is attached to the other motor end bell housing.
They are just Bronze sleeve bearing, cheap! Put a fill drop of oil on the shaft and try to slide the end bell up and down to loosen up.Never stop learning

Re: Do these motor brushes need replaced?
No.can you easily turn the rotor since the rotor is attached to the other motor end bell housing
And it does not make a rough sound when the rotor is turned.
If it is possible, what exact place do I oil?Comment

Re: Do these motor brushes need replaced?
Use http://www.amazon.com/3-IN-ONE-10045.../dp/B00065VGUC
http://www.amazon.com/Markal-79704-S...d_sbs_indust_7
apply it to the shaft and rotate the rotor, clean off any gunk taht comes off, then re-oil it. The end bell in the picture, just put a few drops in the hole.Never stop learning

Hi,
i am asking for some Help.
I have one of these Nescafe Aeroccino (Milk Frother) things with a bad motor.
The Motor didnยดt 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... -
(TL;DR skip the first paragraph)
I encountered my first dead motor run capacitor at a customer this week.
For some fields I guess it is a very common occurrence but the usual way for industrial machines here is to use 3-phase motors.
(Unless a servo motor makes more sense that is).
But for some reason this 3-phase machine uses a 1-phase motor for its liquid coolant pump.
The pump would run but sometimes trip the 10A breaker.
I monitored it starting and stopping for over an hour until it finally stopped in a specific spot between its windings:
Then it could... -
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... -
Got given this breaker to fix, armature had failed so replaced and the same thing happened.
Its a 240v heavy duty breaker as opposed to site 110v.
The 1st armature was bought from aliexpress and advertised as 240v but burnt out within 2 minutes light use taking the 13amp fuse with it and the 2nd bought from ebay (german seller) started to get very hot and begin to smoke so hopefully saved it by shutting it off quick at the first sign of smoke but have now tested the x2 safety cap and its not reading 0.22uf, much lower.
Theres very little to it really on the...08-16-2024, 04:46 AM -
Hoping someone here will be able to provide a few pointers with this. I've got a motor controller board for a device that moves a caravan. A DC motor on each wheel is supplied with 12v DC or -12V DC depending on whether the remote control is pushed in "forward" or "backward" mode. The control is arranged by having 2 relays per motor that, at rest, are all connected to the negative.. If the motor is to go forwards, then relay 1 activates meaning the motor sees "positive negative" on its terminals 1 and 2. If the motor is to go backwards then relay 2 activates meaning...
