Hello everyone.
Customer support is comming.
I will check all links and advices left above. Thank you.
DE side pic below. Startup max vibration is 2.2 mm/sec
Another motors show different startup vibration but lower than 18 mm/sec.
Pump impeller is supported on both sides. Picture below.

It is the horizontal motor.
I reckon, the reason why in the end it doesn't have peak because it slowed down by the pump quickly.
I will measure vibration without load.
Yes I have another pupms nearby with same motors these motors have starting vibration lower than 18 mm/s...
Hello everyone.
I have a AC motor 1250kW 6000V 3 phases. It has a high horizontal vibration of 21-29 mm/s on a non-drive end bearing during the starting time (1-2 sec) at full load.
Then, the vibration is ok , about 1.9 mm/sec.
According to an operation manual the motor can withstand up to...
Hello everybody.
I am trying to analyze lifting eyes welded to a motor. I have analyzed with 2 different methods.
In the first method, I used springs as slings with the setting of behavior - Rigide.
In the second method, I used 3 remote points linked with each other as slings with the setting...
Hello Dear Engineers!
Could you tell me how to calculate a maximum mass of a detail that might be installed at the end of the rotor?
In my case, it is a fan that I want to install at the end of the rotor.
The rotor is installed vertically in two bearings.
I am looking for some source (book or...
As I understand. The maximum balancing weight is limited by two factors.
1. The increase in the entire mass of the rotor does not lead to resonance.
2. The strength of the fastening of the load to the fan at centrifugal force. So that the load does not fly out of the attachment point.
Is it...
Hi everyone.
I am looking for a procedure on how to calculate the maximum permissible mass of one balancing weight?
For example, for a fan that is instaled on the rotor end.
