Baldor Reliance Electric Motor EM4115T

Section 3 — Maintenance general principles

Check the oil level in the sight gauge when the motor is at rest

Check the oil level in the sight gauge when the motor is in operation

Is the oil level at the midpoint of the sight gauge?

Storage — Ball and Roller Bearing Motor Shafts

Rotate motor shafts manually every 3 months

Grease motor shafts every 6 months according to the Maintenance section

Storage — All Other Motor Types, Before Storage

Remove the grease drain plug on the bottom of each bracket before lubricating the motor

Grease the motor with regreaseable bearing as instructed in Section 3

Replace the grease drain plug after greasing

Section 3 — Lubrication Procedure

Ensure lubrication is done with the motor stationary and warm

Prepare the motor for lubrication

Is grease caked around the plug?

Clean caked grease with a wooden stick or suitable tool if present

Is there severe caking at the plug?

Run the motor until the bearing housing is warm to permit free flow of grease if severe caking is present

Locate the motor nameplate to find recommended lubricant type and volume

Section 3 — Periodic Inspection

Listen for any abnormal noises and check cause immediately

Check for any vibration and check cause immediately if excessive vibration is found

Check voltage and frequency variations

Is there unbalanced voltage or single phase operation of poly phase motors?

Check power supply total harmonic distortion to avoid overheating

Periodic checks of phase, voltage, frequency, and power consumption of an operating motor are recommended

Check to see that air filters, when used, are in place and clean

Check all air passages and ensure that they are not blocked or clogged

Section 3 — Lubrication Procedure

Ensure lubrication is done with the motor running, stay clear of rotating parts and electrical circuits

Ensure not to over-lubricate motor

Is the shaft stationary and motor warm for relubrication?

Locate the grease inlet, clean the area and replace the pipe plug with a grease fitting if necessary

Remove relief plug and clean if grease is caked

If severe caking appears, run the motor until the bearing housing is warm

Locate the motor nameplate and find the recommended lubricant type and volume

Record the recommended lubricant type and volume from the nameplate
