What is the difference between a 48Y and 56y frame?
What is 56y frame? 56Y Frame Square Flange Motors are 1/2" wider (body diameter) than 48Y Frame but have Identical hole spacings on the Square Flange. They are inter-changeable. The Square Flange or Face, has 4 - Non Threaded bolt holes at 1, 5, 7 and 11 O'Clock to mate up with the seal plate. Click to see full answer.
What is the frame size of a 56 frame motor?
56 Frame Motors A motor’s frame size is a reference to the size of the mounting footprint, shaft diameter, and shaft length. These motors are all frame size 56. In terms of mounting, these motors can replace each other and other motors with the same frame size.
What is the difference between a 48Y and a flex frame motor?
The Flex-frame motors are usually labeled as 48Y, but will have the distinct pedestal at its base. The Flex is unique because it uses four thin partially threaded screws (known as thru bolts) that are slid the length of the motor through the back end and screwed into the seal plate.
What is the reference number for frame size?
Frame size reference numbers commonly range from 42 to 501 and suffix reference letters from A to Z. The codes 56C & 56J both denote frame size indication and type variation.
What is the difference between 48Y and 56Y frame?
What is the difference between 48Y & 56Y? Both have the same exact size square flange. The 56Y motor body diameter is 1/2″ larger than 48Y, so the 48Y usually includes a 1/2″ rubber spacer if required when mounting. Body diameter is the only difference, they can be inter-changed.
What does 48Y frame mean?
The Flex-frame motors are usually labeled as 48Y, but will have the distinct pedestal at its base. The Flex is unique because it uses four thin partially threaded screws (known as thru bolts) that are slid the length of the motor through the back end and screwed into the seal plate.
What type of shaft does a 56Y frame motor have?
Its large 6.5 frame boasts a stainless steel shaft for extremely durable housing and its thermally protected, Class B insulated design keeps the motor cool to prevent overheating.
What does 56C frame mean?
The codes 56C & 56J both denote frame size indication and type variation. A 56 frame size motor will have a dimension from the rotor shaft centreline to the underside of the motor feet of 3 ½” and a shaft diameter of 5/8”.
What is the difference between 56 and 56h frame?
H — Used on some 56 frame motors, “H” indicates that the base is suitable for mounting in either 56, 143T, or 145T mounting dimensions. J — This designation is used with 56 frame motors and indicates that the motor is made for “jet pump” service with a threaded stainless steel shaft and standard 56C face.
What is a 48z frame motor?
A motor's frame size is a reference to the size of the mounting footprint, shaft diameter, and shaft length. These motors are all frame size 48. In terms of mounting, these motors can replace each other and other motors with the same frame size.
What does the T mean in a motor frame size?
The letter T in a frame size tells you frame number that has been standardized by NEMA so that horsepower, speed, and certain dimensions will be the same for all motors with that frame size. These dimensions include the shaft diameter, shaft height, shaft length, mounting-base dimensions and bolt-hole sizes.
Can I replace a 48 frame spa pump with a 56 frame?
Almost all spa pumps are manufactured in one of two standard frame sizes: 48-Frame and 56-Frame. When replacing your wet end or your motor, you should use an equivalent of the same size, so that the mounting holes on the motor and the wet end align.
What does C face mean on motor?
• C - Designates a “C” face (flange) mounted motor. This is the most. popular type of face mounted motor and has a specific mounting bolt pattern. The critical items on C face motors are the “bolt circle” (AJ dimension), register (also called the rabbet) diameter (AK dimension), and the shaft size (U dimension).
What does 56C mean in motor?
Machine builder Richard J. Kinch says the "C" in "56C" stands for a flange or faceplate mounting system. The four mounting points are on the face of the motor, where the shaft comes out. This mounting arraignment is very useful.
Pool Motor Types
These motors are the new kids on the block, and they are completely different than regular motors, not only in function but also design. They are designed to operate a several different speeds (variable speeds), to reduce energy usage and for performing different tasks (filter, cleaner, fountain).
Pool Motor Frame Types
Also known as 48 Frame, Thru-Bolt motors are used on hot tubs, jetted tubs and aboveground pool pumps. They are distinguished by the built-in pedestal or feet on the bottom of the motor, in addition to their diminutive size. This motor gets it’s name from the four bolts that run through (thru) the motor, from front to back.
How do Pool Pump Motors Work?
The electric motors used on swimming pool pumps operate in the same way as other electric motors around the home. In most cases, pool motors are started with the assistance of a capacitor, until the rotor (or armature) reaches sufficient speed to continue spinning the rotor itself, by the use of magnets.

Where to find frame size of a frame bracket motor?
You can also find the frame size of the motor on the spec sheet, that is located on the side or top of the motor .
How to determine what size frame motor you have?
There are a couple of ways to determine what size frame motor you have, you can either look at the motor spec sheet located on the top or side of the motor, or you can measure between the thru bolts. These are the bolts that run the length of the motor and screw into the four legs of the wet-end volute or seal plate.
