3: L5010‑L5809 frames intended for operation above 3600 rpm on VSD must be reviewed and approved by WEG
4: 364-L5809 frames: Remove and clean bearing caps of excess grease after 8800 hr
Procedure/Warning:
- With the motor shutdown, inject approximately half of the total grease quantity to be used and operate the motor for
approximately one (1) minute in full rotation speed.
- Shutdown the motor and inject the remaining grease. The injection of the entire amount of grease in an idle motor
may cause part of the lubricant to penetrate into the inner part of the motor through the internal sealing of the bearing
cap.
- The lubrication intervals specified consider an absolute temperature on the bearing of 149°F (65°C) the motor running
at rated speed, a motor mounted in horizontal position and greased with appropriate grease based on table above. Any
variation of the parameters listed above must be evaluated by WEG engineering.
- For each increment of 27°F (15°C) above the bearing temperature, the relubrication intervals given in Table 11 must be
halved. For special applications such as: high and low temperatures, aggressive environments, vertical mounting posi -
tion for example, contact WEG about the required amount of grease and the relubrication intervals
.
Note: This motor lubrication schedule is for WEG electric motors only. For other manufacturers, follow their schedule
