48z frame motor dimensions

This Marathon 48A11O direct drive permanent split capacitor motor is single phase with three-speed operation.

Replace old base-mount motors to keep your equipment moving. Motors are rated for continuous duty and mount at any angle. You can wire for clockwise or counterclockwise rotation; instructions are included. Motors with a vibration - damping base have rubber rings between the base and enclosure to minimize vibration. Motors with overload protection turn off in overload conditions to prevent motor damage. Automatic overload protection starts the motor automatically after it cools.

When it comes to replacing a motor, frame size is an important factor to get right. Manufacturers have collaborated to standardize frame sizes to allow motors to be more easily replaced, meaning you can swap a Baldor motor for a WEG motor and vise versa, assuming all the other specifications align. Standard frame sizes for motors with the same HP, speed, and enclosure to be replaced with motors with the same ratings but from different manufacturers. Motor frame size standardization happened in three stages. All frame sizes up until are referred to as original frame sizes. A large standardization took place in , these frame sizes are referred to as U-Frames. And then a final standardization took place in , these frame sizes are referred to as T-Frames. Many original frame sizes and U-frames are still in action today and will eventually disappear as those motors are replaced. There are two groups that have individually contributed to the standardization of electric motors, their ratings, and their sizes. The International Electrotechnical Commission, also known as IEC, completed the standardization of motors for the rest of the world, namely Europe. NEMA assigns the frame sizes based on enclosure, horsepower, and speed. As you can see in the chart below, the frame sizes are quite close, but often out by 3 or 4 mm, which is a large enough difference to make the motors not interchangeable. You may have noticed that fractional horsepower motors have fewer numbers in their frame size as compared to integral horsepower motors 1 HP and above.

Some of these items ship sooner than the others. This is measured through the centerline from the bottom of the base.

Feb 8, Electric Motor Repair. Many have been in the situation where you needed a specific frame only to realize it was made with a special shaft or has a mounting flange, but no one knew how to find this information! For example, if you have a T frame motor, every manufacture of motor will have the same shaft diameter, shaft length and bolt hole mounting dimensions, but be warned, your physical size of the motor may differ. There are other common letter suffixes that are also standard. The rest of the letter designations get a little more difficult and can mean anything from how the motor is mounted to special non-NEMA regulated shaft dimensions. This indicates that the motor has special mounting dimensions, which must come from the manufacture of the motor.
