NEMA ODP Single Phase Electric Induction Motor
ODP (Open Drip Proof): An open motor in which the ventilating openings are so constructed that drops of liquid or solid particles falling on it, at any angle not greater than 15 degrees for the vertical, cannot enter either directly or by striking and running along a surface of the motor and designed for reasonably dry, clean, and well ventilated (usually indoors) areas. Outdoor installations require the motor to be protected with a cover that does not restrict airflow to the motor. NEMA ODP series are single-phase rolled-steel motors with open drip proof, ac motors, and induction motors. The electrical motors are developed by ourselves independently, according to NEMA. The output-rated power and mounting dimensions of the electrical motor are perfect by NEMA. The NEMA ODP motors have reasonable structure, slight vibration, and low noise; they are made in china.

TEFC motors are generally more expensive. This is because they contain extra equipment — the fan — and they serve a specialized purpose. Also, TEFC motors have a thinner, larger casing to allow for better heat dissipation, which adds to the cost.

Differences Between NEMA and IEC Electric Motors
IEC motors are commonly made with either finned cast aluminum or iron frames, while NEMA motors are made with finned cast frames and rolled steel frame housings. There are only slight differences in frame sizes based on shaft height. The shaft diameters and lengths are different between NEMA and IEC, as are the mounting base dimensions and mounting hole spacing.
If a plant’s motor population is mixed between NEMA and IEC, care must be taken when someone is sent to regrease motors. A significant difference is that NEMA motors commonly use polyurea-based grease, whereas most IEC motors use lithium grease. These greases are not compatible and should not be mixed.
Typically, NEMA motors are made with a side-mounted conduit box (F1 position) with leads for connections. Most IEC motors have the conduit box at 12 o’clock (F3) with a terminal block for connections.
NEMA motors usually do not have a shaft seal except for some severe-duty designs, such as those made for IEEE-841 compliance, where a noncontact rotating shaft seal is used. In some custom designs, a lip seal may be used on the shaft to prevent the ingress of liquids. Many IEC motors are supplied with a standard lip seal.
NEMA motors often have a “weep hole” at the lowest point of each end plate to allow condensation to exit. On severe duty motors, this hole is changed to a breather drain. This practice is not standard on IEC motors.
Over the past few years, NEMA has adopted IEC standards as part of MG 1. The levels of ingress protection (IP) for motors and cooling (IC) are shown in the MG 1 standard. Recently, the vibration standards have been harmonized.
