How do you measure a motor frame size?

How do you measure a motor frame size?

Just divide the first two digits by four. Thus, a 405 frame (original, U frame, or T frame) has a shaft height of 40 divided by 4, or 10 in. Although no direct inch measurement relates to it, the third digit of three-digit frame sizes is an indication of the motor body’s length.

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 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.

What is a 48 frame motor?

48-Frame motors are basically pool motors, not designed for the rigors of hot tubs with their high-pressure massage jets. Specifically “Frame” refers to the diameter of the armature in the motor. Although 2 motors may have the same horsepower rating, a 56-Frame motor will be 40% larger.

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 JM mean on motor frame?

• JM – The letters JM designate a special pump shaft originally designed for. a “mechanical seal.” This motor also has a C face. • JP – Similar to the JM style of motor having a special shaft, the JP motor. was originally designed for a “packing” type seal.

What does 56C frame mean?

Machine builder Richard J. Kinch says the “C” in “56C” stands for a flange or faceplate mounting system. The four mounting points are on the face of the motor, where the shaft comes out. This mounting arraignment is very useful.
