Frequent question: What is frame size in induction motor?

What is frame size in motor?

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 does frame number mean?

The frame number relates to the “D” dimension (distance from center of shaft to center bottom of mount). For example, in the two-digit 56 frame, the “D” dimension is 3½”, 56 divided by 16 = 3½”. For the “D” dimension of a three-digit frame number, consider only the first two digits and use the divisor 4.

What is page frame number?

A block of RAM, typically 4KB in size, used for virtual memory. A page frame is a physical entity with its own page frame number (PFN), whereas a “page” is content that floats between memory page frames and storage (disk or SSD).

How do you measure engine frame size?

The frame number relates to the “D” dimension (distance from center of shaft to center bottom of mount). For example, in the two-digit 56 frame, the “D” dimension is 31/2”, 56 divided by 16 = 31/2”.

What does TC mean on motor frame?

What is the difference between a 48 frame and a 56 frame?

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 48 frame motor and a 48Y frame motor?

The only difference between the 56Y and 48Y frame is the circumference of the motor. They will both mount to the seal plate of the pump.
