What is DE and NDE in motor?

What is DE and NDE in motor?

ccw. DE – Drive End. NDE – Non Drive End. cw – clockwise.

What is motor management?

Motor management is about managing motors as an asset, not as individual products. It involves planning ahead, making decisions before a motor fails and considering the true cost of operating motors to save energy, reduce downtime and increase profitability.

How do I know if my electric motor has sealed bearings?

When trying to decide whether a bearing is sealed using the AFBMA or SKF code, note the shields or seals section. If the bearing number uses the AFBMA code, look for “EE” (or “2RSI” for SKF) to determine if the bearing is sealed on both sides. This is the only way to identify whether a bearing is sealed.

What is non drive end of motor?

Non-drive end motor brakes are brakes that are mounted on the non-drive end of the motor making them ideal for industrial environments that require more space or motor systems that rely on a set of specific braking system criteria.

What is DE and NDE in generator?

DE = Drive End. NDE = Non- Drive End. Direction of rotation is always given looking onto the DE. 1.2 Identification. Generator nameplate.

Why do motors need Relays?

Relays are used to control small loads of 15 A or less. In motor circuits electromechanical relays are often used to control coils in motor contactors and starters. Other applications include switching of solenoids, pilot lights, audible alarms and small motors ( 1/8 hp or less).

Should you lubricate a sealed bearing?

FOR STARTERS, note that most sealed bearings come pre-greased from the factory with a 25%-35% grease fill. This is all the grease the bearings will ever need, because the relubrication interval (explained below) is longer than the expected life of the bearing.

What is drive and non drive end?

The drive end bearing often must take significant radial load. The non drive end does not. The load comes from pulleys, gears or the weight of a suspended load rotating component. This requires a stronger bearing to avoid earlier failure.

What is motor drive end?

The back end of a normal motor is the end which carries the coupling of driving pulley. ( NEMA) this is sometimes called. the drive end (D.E., pulley end P.E.) etc. Base End of a Motor: The speed which a d-c motor develops at rated armature and field voltage with rated load applied.

What is end shield in motor?

Endshield: That part of the motor housing which supports the bearing and acts as a protective guard to the electrical and rotating parts inside the motor. This part is frequently called the “end bracket” or “end bell”.
