What is DE and nde in motor?

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

What causes power to flow through an AC motor?

As the coils are energized, the magnetic field they produce between them induces an electric current in the rotor. This current produces its own magnetic field that tries to oppose the thing that caused it (the magnetic field from the outer coils). The interaction between the two fields causes the rotor to turn.

How does a motor work with AC current?

An AC motor is an electric motor that uses alternating current to produce mechanical energy using magnetism blended with alternating current. The structure of an AC motor includes coils that produce a rotating magnetic field inside a rotor attached to an output shaft, which produces a second magnetic field.

What is DE and ODE bearing?

Types of Bearings The most common bearing found in horizontal foot mount electric motors is the Single. Row Deep Groove Ball Bearing. This bearing is used in most motors on the Opposite. Drive End (ODE) and on the Drive End (DE). Another common bearing is the Cylindrical Roller Bearing.

What is driven end and non driven end?

Turbine ends are inlet and exhaust, driven machinery such as a compressor or generator have a driven/drive end which is coupled to the prime mover, and a free/non drive end at the other. Diesel engines would be free end and thrust end, though it could be termed “driving end”.

How do you tell if a bearing is sealed or not?

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.

How do you find the bearing on a motor?

Take a look at the Equipment Builder (EB) Plate, or more specifically the two serial numbers at the top of the plate: These numbers, labeled “SHAFT END BRG” and “OPP END BRG,” describe the bearings within the motor.

What is De and Ode?

Drive End (ODE) and on the Drive End (DE). Another common bearing is the Cylindrical Roller Bearing. Many other bearing types exist but are not commonly used on typical motors found in a mill or plant.

What is drive end of motor?

The back end of a normal motor is the end that carries the coupling or driving pulley (NEMA). This is sometimes called the drive end (D.E.), pulley end (P.E.) etc. (See page 2.) The speed in revolutions per minute (RPM) which a DC motor develops at rated armature and field voltage with rated load applied.
