What is the frame size of an electric 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. The method of measurement and the requirement Page 9 IS 12615 : 2011 4 shall be as given in 8.6 of IS/IEC 60034-1 and 5.7 of IS 15999 (Part 2/Sec 1).
What are the different sizes of electric motors?
1, 1.5, 2, 3, 5, 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 75, 100, 125, 150, 200, 250, 300, 350, 400, 450, 500, 600, 700, 800, 900, 1000, 1250, 1500, 1750, 2000, 2250, 2500, 3000, 3500, 4000.
What is IEC motor frame size?
IEC Quick Reference Chart
| Frame Size | A | E |
|---|---|---|
| 63 | 100 mm | 23 mm |
| 71 | 112 mm | 30 mm |
| 80 | 125 mm | 40 mm |
| 90S 90L | 140 mm | 50 mm |
What is the difference between a 48 frame motor and a 56 frame motor?
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 does the frame number mean on a 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 is IEC frame?
The IEC 72 defines motor frame size standards for regions that use SI units. Regions using “inch” units work with NEMA standards (see page NEMA Frame Size). Therefore most motor series are offered with both standard frame sizes.
What is the diameter of a 48 frame motor?
| NEMA FRAME | D* | U> |
|---|---|---|
| 48H | 3 | 1/2 |
| 56 | 3 1/2 | 5/8@ |
| 56H | 3 1/2 | 5/8@ |
| 56HZ | 3 1/2 | 7/8 |
Can I replace a 48 frame spa pump with a 56 frame?
Hot tub pumps typically come in two different frame sizes: 48 frame and 56 frame. When replacing a hot tub pump, it is important to replace it with the same size pump so that the holes and plumbing will line up.
What is the difference between NEMA and IEC motors?
NEMA caters to large-sized devices in North American Markets only. IEC ratings are for more compact devices in the global market. IEC ratings react faster to overloads while NEMA ratings withstand short circuits. IEC devices are safe to the user, while NEMA devices require safety covers.
What does frame size mean on a motor?
The frame size of a motor defines its mechanical interface to attached actuators. Motors of the same frame size can have different power, torque etc. but feature the same geometrical properties. The length of the motor housing is not affected by the frame size.
What is difference between 48 and 56 frame motor?
What does NEMA mean on a motor?
The National Electrical Manufacturers Association
The National Electrical Manufacturers Association (NEMA) has established class designations for motors on the basis of motors’ starting-torque and accelerating loads.
What does 48 and 56 frame motor mean?
What is the power output of a TECO motor?

What is the base material of a TECO stator?
TECO utilises mica tape as its base material, which is impregnated with a special epoxy resin. Impregnation is accomplished by immersion of the completely assembled stator in the special resin using a vacuum pressure cycle.
