What is a 48Y 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 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.
How do you measure Ed frame?
A: Measure the longest horizantal distance inside the frame edges in mm. B: Measure the longest vertical distance inside the frame edges in mm. ED: Measure the longest diagonal distance inside the frame edges in mm.
How big is a fractional horsepower motor frame?
FRACTIONAL HORSEPOWER MOTORS The term “fractional horsepower” is used to cover those frame sizes having two digit designations as opposed to the three digit designations that are found in Tables 1 and 2. The frame sizes that are normally associated with industrial fractional horsepower motors are 42, 48, and 56.
How tall is the shaft of a 48 frame motor?
The derivation of the two digit frame number is based on 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 inches. Similarly, a 56 frame motor would have a shaft height of 3-1/2 inches.
How tall is a 254T motor shaft in inches?
shaft height (“D” dimension) above the bottom of the base is the first two digits of the frame size divided by four. For example, a 254T frame would have a shaft height of 25 ÷ 4 = 6.25 inches. Although the last digit does not directly relate to an “inch” dimension, larger numbers do indicate that the rear bolt holes are
How tall is the centerline of a 254T frame?
It is that the centerline shaft height (“D” dimension) above the bottom of the base is the first two digits of the frame size divided by four. For example, a 254T frame would have a shaft height of 25 ÷ 4 = 6.25 inches.
