What kind of grease is used in electric motors?
A NLGI 2 grade grease is the most commonly used in electric motor applications. ASTM D 3336 oxidation life. require a grease with an EP additive. Dropping Point: The dropping point gives an indication of the temperature at which the grease will melt or the oil will separate from the thickener.
How often should you grease a Baldor electric motor?
Table 3 specifies 9500 hours as the recommended lubrication interval for frame sizes 254 to 286 (see nameplate), given standard service conditions. Multiply. 5 (service condition multiplier value) by 9500 hours (recommended lubrication interval) = 4750 hours (calculated lubrication interval).
How often should you grease a motor?
When the operating temperature is between 80°C – 100°C (176°F – 212°F), oil should be replaced at least every three months. For critical equipment, it is advisable that lubricating oil be analyzed at least every three months to determine when oil replacement is necessary.
How do you grease an electric motor?
Electric Motor Bearing Lubrication Procedure
- Ensure the grease gun contains the appropriate lubricant.
- Clean the areas around the relief and fill fittings.
- Remove the grease relief valve or drain plug.
- Grease the bearing with a calculated amount of grease.
- Watch for grease coming out the relief port.
Is Lithium grease good for electric motors?
The grease consistency preferred for electric motors is normally NLGI 2 or 3, with a base oil viscosity of 100-150 cSt @ 40°C. A polyurea thickener system is preferred for most electric motor applications, but grease with an aluminum complex, lithium complex or calcium sulfonate thickener are also good options.
What is the difference between NLGI 1 and NLGI 2 grease?
There are two basic types of grease for most equipment and machinery applications: NLGI #1 grease and NLGI #2 grease. So what’s the difference? Less thickener makes a #1 grease more tractable and slippery, while #2 grease has more thickener, making it stiffer and great for all-purpose applications.
Can you over grease bearings?
Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.
How often should I oil my fan?
The mechanism that rotates the fan blades has bearings that ensure smooth, noise-free operation. But when the bearings rub against one another, the friction generated gradually wears them down. Some ceiling fan models are designed to be lubricated by the user, and if you have one of these, you should do so once a year.
Do sleeve bearings need lubrication?
Factory-fresh motors with sleeve bearing systems are always properly lubricated. Since it is essentially a closed system, there is no chance the oil will leak out during shipping or installation, so avoid the temptation to oil the motor when you put it in.
What happens if you over grease an electric motor?
Over lubrication can cause the grease or oil to get into the windings. This will cause the insulation to deteriorate around the winding, resulting in arcing and shorting inside the motor to the case. Over lubricaiton will also cause excessive heat and wear on the rotor and stator.
What does the NLGI number of grease indicate?
The NLGI number is a measure of the grease’s consistency as indicated by its worked penetration value. The higher the consistency, the more resistant the grease is to releasing lubricating fluid under force. A grease with a low consistency will release lubricating fluid more readily.
Do Baldor motors come pre greased?
The bearings have been lubricated at the factory. Motors that do not have regrease capability are factory lubricated for the normal life of the bearings.
Can I use wd40 on fan motor?
[ Never put WD-40 in] any electric motor, even if the rotor is stuck from filthy dried-up lubricant! It not only removes any remaining lube, but it can melt coil wires (the lightly-coated copper wires twisted up in electric motors) and cause an electrical short.
Can you use wd40 on an electric motor?
It’s a great cleaner, but it’s not a good lubricant. You should be fine if you use it to clean. The motor will fail if wd-40 is used.
