What is the motor frame size?
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.
How do you read motor frame size?
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 TS mean on motor frame?
Short shaft motors can easily be identified by a “TS” after the frame number and are typically used for direct coupled loads. A flexible coupling is used between the motor and the driven load. These motors are not designed for radial loads which would be imposed by belt, or chain applications.
What size is a 48 frame motor?
NEMA T FRAME DIMENSIONS
| Nema Series | D | H |
|---|---|---|
| 48 | 3 | 11/32 Slot |
| 56 56H | 3 1/2 | 11/32 Slot |
| 143T 145T | 3 1/2 | 11/32 |
| 182T 184T | 4 1/2 | 13/32 |
What is a 184 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 184. In terms of mounting, these motors can replace each other and other motors with the same frame size.
What are 4 common types of motor enclosures?
The Most Common Types Of Electric Motor Enclosures
- The most common types of enclosures are:
- Open Drip Proof (ODP)
- Weather Protected (WP1 / WP2)
- Totally Enclosed Fan Cooled (TEFC)
- Totally Enclosed Non-Ventilated (TENV)
- Totally Enclosed Air Over (TEAO)
- Totally Enclosed Forced Ventilated (TEFV)
- XP (Explosion Proof)
What is C face motor?
A “C-Face” motor is a common American mechanical standard designed with a rugged flange on the face of the motor for mounting purposes. The weight of the. motor is supported by the flange, which is most commonly attached to a gearbox.
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’s 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.
