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 frame size of motor?
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.
What size is a 48 frame motor?
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 the difference between 48 Frame and 56 Frame motor?
Contact us to find an authorized spa repair technician near you. The main difference between a 48 frame and a 56 frame hot tub pump is that the 48 frame has a smaller motor housing and so the 4 through bolts that fasten the wet end to the motor are closer together on the smaller motor.
What is the difference between a 56 and 56c frame?
it depends on the motors frame size, the one in the link is a FRAME 56C, the “C” stands for c faced, the 56 frame is a very popular frame, and used on many many motors, but I can not tell you if the gear box will fit with out either measurements or what face it is designed with.28 мая 2008 г.
What does TC mean on motor frame?
Three-Phase Cast Iron
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 is the difference between 48y and 56y frame?
The only difference between the 56Y and 48Y is the circumfrence (width) of the motor. They will both mount to the seal plate but the 48Y will need an optional spacer (that comes with the motor) to sit on to make up for the difference in size.
What is frame size?
Body frame size is determined by a person’s wrist circumference in relation to his height. For example, a man whose height is over 5′ 5″ and wrist is 6″ would fall into the small-boned category.
How do you measure a motor shaft?
The frame number relates to the “D” dimension (distance from center of shaft to center bottom of mount). For a two digit frame divide the frame number by 16 to arrive at this dimension. For example, in the two-digit 56 frame, the “D” dimension is 3½” (56 divided by 16 = 3½”).
What is a 56c frame motor?
1/3rd to 3 HP 1800 and 3600 C flange with removable feet, our 56C Frame motors are suitable for a variety of commercial/industrial applications. 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.
What does C face motor mean?
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.
Are hot tub pumps interchangeable?
Most spas will be the same size for both the intake and outtake pipe, but double check just in case. Most spa pumps use 1.5” or 2” plumbing fittings. With all this information in hand, you should be able to select a new hot tub pump as a replacement.
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.
What type of shaft does a 56y frame motor have?
The motor shown is a 56Y frame. (Square with Threaded Shaft) – Y-frame motors feature a square metal flange for bolting to the pump housing. The frame you have is a 56Z. Z (Round Flange with Flat Shaft) – The Z-frame uses a flatted shaft end on which the impeller is to be secured.
