Baldor Reliance Electric Motor 10840-AF-TEFC

Section 1 – Storage (less than 6 months)

Ensure grease lubricated bearings are not lubricated during storage

Verify Duty Master anti-friction bearing motors are shipped with the proper amount of grease in each bearing

Remove packing to expose the shaft and remove the shaft shipping brace every 30 days

Rotate the shaft by hand 10 to 15 revolutions to distribute grease or oil

Replace protective packing and shaft shipping brace after rotating the shaft

Inspect the motor periodically and check insulation resistance monthly

Is the storage location cold, damp, or humid?

Is the motor stored and directly exposed to weather conditions?

Section 3 – Semi-Annual Maintenance − 6 months

Perform all quarterly inspections (see 3 Monthly Motor Periodic Inspection task)

Inspect and clean rotor ends, windings and fan blades (Open Motors only)

Check electrical connections for tightness and absence of corrosion

Section 3 – Winding Maintenance

WARNING — Solvents can be toxic and/or flammable — follow manufacturer's safety procedures and directions — failure to observe this precaution could result in bodily injury

CAUTION — Do not use solvents containing trichloroethane to clean interior or exterior of motor — damage may occur to paint and insulation systems

Disconnect and lockout the power source

Ensure no power is applied to the motor

Section 3 – Sleeve Bearings (Oil Lubricated)

Select lubricating oil based on conditions

Avoid using automotive oils or unapproved additives

De-energize the motor by opening the manual disconnect switches

Remove drain plug and drain oil

Flush out the housing by filling with fresh oil and drain again if oil is contaminated

Section 3 – Anti-Friction Bearing (Grease Lubricated) – Severe Conditions

Do not over-lubricate motor as this may cause premature bearing failure

Over-lubricating can cause excessive bearing temperatures, premature lubrication breakdown and bearing failure

To avoid damage to motor bearings, grease must be kept free of dirt

Relubrication with the shaft stationary and a warm motor is recommended

If lubrication must be done with motor running, stay clear of rotating parts and electrical circuits

Locate the grease inlet, clean the area and replace the pipe plug with a grease fitting, if the motor is not equipped with grease fittings

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

Check power supply total harmonic distortion to avoid overheating

Perform periodic checks of phase, voltage, frequency, and power consumption of an operating motor

Check that air filters are in place and clean

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

Check for proper lubrication and oil level in sleeve bearing motors
