A “C-Face” motor is a common American mechanical standard designed with a rugged flange on the face of the motor for mounting purposes. The weight of the. motor is supported by the flange, which is most commonly attached to a gearbox. The flange is strong enough to cantilever the motor.
What is NEMA C face?
NEMA C-face brakes are designed to allow for direct mounting with coupled equipment. … They are commonly used on pump, oil burners and gear reducers.
What does TC mean on motor frame?
Three-Phase Cast Iron T-Frame. TC-Frame (C-Face) TEFC Motors – Three-Phase Industrial Duty – 1 to 100 hp.
What is IEC in motor?
The IEC is the standard for electric motors for the rest of the world. Similar to NEMA, IEC publishes Standard 60034-1:2010, the standard outside North America. NEMA and IEC motors are similar in size, efficiency and output power. Both also have standards in place to designate: Frame size dimensions.
What is meant by frame size?
NEMA (National Electrical Manufacturers Association) frame size refers to mounting only and has no direct bearing on the motor body diameter. In any standard frame number designation there are either two or three numbers. Typical examples are frame numbers 48, 56, 145, and 215.
How do I find out my motor frame size?
The two-digit frame number relates to the shaft height in sixteenths of an inch. You can figure that a 48-frame motor will have a shaft height of 48 divided by 16, or 3 in. Similarly, a 56-frame motor has a shaft height of 3.5 in.
What is a 56C frame motor?
These NEMA 56C Frame motors have removable bolt on/bolt off bases with mounting holes punched for NEMA 56 and NEMA 143T and NEMA 145T applications. … The shaft is standard 5/8th diameter and made of a high grade tensile strength steel.
What is the difference between 48y and 48yz frame?
Y (Square with Threaded Shaft) – Y-frame motors feature a square metal flange for bolting to the pump housing. … The J-frame features a threaded shaft for impeller installation. C (Round Flange with Keyed Shaft) – These motors have a notch that runs the length of the exposed motor shaft that is called a key.
What size is a 48 frame motor?
The derivation of the two digit frame number is based on the shaft height in sixteenths of an inch. You can figure that a 48 frame motor will have a shaft height of 48 divided by 16 or 3 inches. Similarly, a 56 frame motor would have a shaft height of 3-1/2 inches.
What is IEC frame size?

What is difference between IEC and NEMA?
NEMA caters to large-sized devices in North American Markets only. IEC ratings are for more compact devices in the global market. IEC ratings react faster to overloads while NEMA ratings withstand short circuits. IEC devices are safe to the user, while NEMA devices require safety covers.
What is an IEC motor starter?
IEC starters include single phase detection, and faster reaction to overload conditions, while NEMA devices can more easily withstand short circuits. NEMA starters have an open design, so often safety covers are required, while IEC contactors and starters are inherently finger safe.
What is the difference between ODP and Tefc Motors?
An open drip proof or ODP motor is a type of motor that typically runs cooler and does not overheat. … On the other hand, a totally enclosed fan cooled, or TEFC motor has a closed off chamber which requires the use of an external fan to blow air over it.
What does a bike size mean?
The bike measurements are given for the frame of the bike, which, for road and mountain bikes, is the distance from the top of the seat tube (rather than the seat) to the center of the bottom bracket. … You can download frame size charts from eBicycles also.
What is the frame of a bike?
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the diamond frame.
What is NEMA motor size?
Step motors are categorized by NEMA frame size, such as “size 11” or “size 23” or “size 34”. Generally speaking, a size 11 step motor means the mounting face of the motor is 1.1 inches square; A size 23 step motor is 2.3 inches square; A size 34 step motor is 3.4 inches square, etc.
