What is a 48 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.
How do you measure a motor frame size?
Just divide the first two digits by four. Thus, a 405 frame (original, U frame, or T frame) has a shaft height of 40 divided by 4, or 10 in. Although no direct inch measurement relates to it, the third digit of three-digit frame sizes is an indication of the motor body’s length.
What size is a 56 frame motor?

What does 48 frame in a pool pump mean?
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.
What does 48 frame pump mean?
Often with an F indicating that is the “frame” size. If you cannot find an indication of frame size you can measure between the thru-bolts on the pump. A 48 frame will be less than 4 inches between the bolts; a 56 frame will be more than 4 inches between the bolts.
What is the frame size of a motor?
The frame sizes that are normally associated with industrial fractional horsepower motors are 42, 48, and 56. In this case, each frame size designates a particular shaft height, shaft diameter, and face or base mounting hole pattern.
Is standard for motor dimensions?
The dimensions of the motors shall be as specified in IS 1231, IS 2223 and IS 2254 as applicable.
What is the motor size?
Motor Sizing Motor sizing refers to the process of picking the correct motor for a given load. It sis important to size a motor correctly because: a. If a motor is too small for an application it may not have sufficient torque to start the load and run it up to the correct speed.
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. If you want to replace your wet end or your motor, you should use an equivalent of the same size, so that the mounting holes between the motor and the wet end align.
What is IEC frame size?

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 frame 56?
Sort & Filter. 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 a YZ motor frame?
“YZ” means that the motor has been changed and no longer follows these rules. The shaft may be different, ie, longer, shorter, diameter, threaded, ect. And as a. result is no longer a “standard” motor. All Dimensions in inches.
What does 56C frame mean?
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.
What is AZ frame motor?
Take “Z” for example, this means there was special machining done to the shaft to make it different from the standard stocked motor.These motors are many times referred to as Above-NEMA or ANEMA Motors since there isn’t a NEMA frame to match to.
What is 56J frame motor?
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 type of motor is a 48Y?
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 does FR mean on electric motor?
FR or FRAME – Frame Designation -This is typically a two- or three-digit number followed by one or more letters that identifies important mounting dimensions for the electric motor. HP or kW – Horsepower or Kilowatt output of the motor. HZ – The frequency of the motor expressed in hertz. INS.
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 is meant by frame size?
Frame size generally refers to frame height, the length of the seat tube from the bottom bracket (crank bearing) to the top tube.
