Quick Answer: What Does NEMA Frame Size Mean?

What does TC mean on motor frame?

Three-Phase Cast IronThree-Phase Cast Iron T-Frame.

TC-Frame (C-Face) TEFC Motors – Three-Phase Industrial Duty – 1 to 100 hp..

What is the difference between Nema 23 and Nema 34?

The decision between NEMA 23 and NEMA 34 motors is primarily a decision about productivity — NEMA 34 motors can remove material at a higher rate using higher feed rates and deeper cut depths. … NEMA 34 motors can take deeper passes through material and improve cutting speeds, especially on larger machines.

What is a NEMA configuration?

The National Electrical Manufacturers Association (NEMA) has assigned designations to the various configurations. The purpose of so many different types is to prevent the wrong combinations of electrical systems from being plugged together, thereby avoiding potentially dangerous conditions.

What is the difference between Nema 23 and Nema 24?

Nema 23 means a 2.3″ frame. Nema 24 means a 2.4″ frame. That’s all. Either could have more or less torque depending on speed and power.

What does NEMA 17 stand for?

Stepper motorStepper motor. another NEMA-17 size motor. A NEMA 17 stepper motor is a stepper motor with a 1.7 x 1.7 inch (43.18 x 43.18 mm) faceplate. The NEMA 17 is larger and generally heavier than for example a NEMA 14, but this also means it has more room to put a higher torque.

What is frame and frame size in case of induction motor?

In fractional horsepower motors the frame sizes are two digits and represent the shaft height of the motor from the bottom of the base in sixteenths of an inch. For example, a 56-frame motor would have a shaft height (“D” dimension) of 56/16 of an inch, or 3.5 inches.

What is motor frame size?

NEMA (National Electrical Manufacturers Association) frame size refers to mounting only and has no direct bearing on the motor body diameter. … By NEMA definition, two-digit frame numbers are fractional frames even though 1 HP or larger motors may be built in them.

What is NEMA standard for motors?

NEMA is the North American standard for electric motors. NEMA is the publisher of NEMA MG 1-2014, a book that defines the manufacturing standards for alternating-current (AC) and direct-current (DC) motors in North America. The IEC is the standard for electric motors for the rest of the world.

What size stepper motor do I need?

Harder materials will need a more powerful stepper because the cutting bit is being driven into the material. If you intended to cut very hard materials then high torque steppers motors will be required usually around 300-400 oz/in and you may need to go up to NEMA34 and you will need a strong frame to support that.

What is IEC standard for motor?

The International Electrotechnical Commission (IEC) has introduced standards relating to energy efficient motors. IEC 60034-2-1 specifies rules concerning efficiency testing methods and IEC 60034-30 defines efficiency classes for a wide range of electric motors connected direct on line.

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.

What NEMA 17?

NEMA 17 is a hybrid stepping motor with a 1.8° step angle (200 steps/revolution). Each phase draws 1.2 A at 4 V, allowing for a holding torque of 3.2 kg-cm. NEMA 17 Stepper motor is generally used in Printers, CNC machines and Laser Cutters.

What is NEMA 23 frame size?

NEMA 23 is a stepper motor with a 2.3×2.3 inch (58.4×58.5 mm) faceplate and 1.8° step angle (200 steps/revolution). Each phase draws 2.8 A at 3.2 V, allowing for a holding torque of 19 kg-cm. NEMA 23 Stepper motor is generally used in Printers, CNC machine, Linear actuators and hard drives.

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 do NEMA numbers mean?

The NEMA (National Electrical Manufacturers Association) pattern and numbering system is made up of four main identifiers. … The second identifier is a number. The first number in a NEMA listing determines the voltage rating. A 5 represents a voltage rating of 125 VAC, while a 6 identifies a rating of 250 VAC.

What is a 48 frame motor?

48-Frame motors are basically pool motors, not designed for the rigors of hot tubs with their high-pressure massage jets. … Specifically “Frame” refers to the diameter of the armature in the motor. Although 2 motors may have the same horsepower rating, a 56-Frame motor will be 40% larger.

How do you determine engine 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.
