Re: id fan motor bearing temp problem
Heating phenonomenon occoured in bearing is known as 'Seizing'
Most common reasons of bearing seizure are as follows.
Improper lubrication (Check lubricant type, quantity, quality and life.)
Possible entry of water or debris in lubricant.( Replace lubricant and improve sealing)
Improper contact of rolling elements with roleway surfaces.(Inspect bearing)
Excess rotational speed.(Decrease speed if excessive)
Ambient T high b/c of high T at PH fan inlet.( Make some insulation or external cooling to avoid heat from the reach of bearing.)
Excessive shaft bending.
U can have an external cooling fan to prevent frequent tripping of PH fan,
Hope u get some help
Have a nice day.
