Fan maintenance
Even large fans like this 120mm mains powered unit have the same bearing arrangement as much smaller models Apart from the danger of equipment failure caused by a dead fan you can't always easily replace a fan if it fails So it pays to keep unusual fans oiled This little fan in a network switch doesn't look all that weird
3 Problems that Can Cause Your Vacuum to Be Unusually Loud
If the bearings on the electric motor have worn because of lack of grease they will wear unevenly and grind against each other and the bearing rings This sort of grinding is very serious and the machine should not be used until the problem has been repaired In extreme cases damaged bearings may become very hot and melt the plastic housing

Electrical and Mechanical Noise in Motors
An electrical noise could be reduced by fitting a capacitor or a choke coil to a motor terminal part However in order to reduce spark or voltage generated by a spark these parts are to be fixed to the armature which enables to eliminate the noise more effectively fixing parts closer to the armature sometimes contributes to the lower cost policy

Ball Bearing Noise and Vibration
Ball Bearing Noise and Vibration Excessive vibration will increase bearing noise and can drastically shorten the life of a bearing Bearing rings and balls are not perfectly round and the balls and raceways even after extensive fine grinding and polishing are not perfectly smooth There are machining imperfections in the form of rough or
How to Diagnose Lawnmower Engine Noises
A lawnmower has many moving parts and when something is wrong it can begin to make funny noises The noises being produced can be a clue as to what is the problem Common noises that mean there is a problem include squealing low pulsing noises shuddering noises high pitched vibrations or
How To Repair Air Conditioner That's Making Noise
The opposite end of the motor has a fan blade that is used to dissipate the heat from the condenser coil When your air conditioner is on the fan motor runs almost continually and over time the motor bearings or bushings may wear out and develop an unusual squeaking screeching or roaring noise

How to Stop an Electric Motor From Squealing
An electric motor generally runs maintenance-free for many years It has only one moving part the armature which has one or more wire windings wound around the central section The end spindles on the armature are seated between bearings which enable the motor to rotate smoothly and quietly
DC motor
Ball bearing motor – A ball bearing motor is an unusual electric motor that consists of two ball bearing-type bearings with the inner races mounted on a common conductive shaft and the outer races connected to a high current low voltage power supply An alternative construction fits the outer races inside a metal tube while the inner
Types of Bearings
In a ball bearing the load is transmitted from the outer race to the ball and from the ball to the inner race Since the ball is a sphere it only contacts the inner and outer race at a very small point which helps it spin very smoothly But it also means that there is not very much contact area holding that load so if the bearing is overloaded the balls can deform or squish ruining the
Bad Bearings: Replace them or the entire pump?
Feb 04 2010I called a pool guy and he said my bearings were shot So it looks as if I have 3 choices: 1) Replace the bearings 2) replace the motor or 3) replace the whole pump Pool Guy thinks that I should replace the whole pump with a 1 5hp WhisperFlo which he would do for $850
