What is F1 motor mounting?

The standard mounting position is F1 by NEMA standards for industrial mounts. This position is where the junction/conduit box is located on the left side of the motor facing the output shaft. This is the probably the most popular configuration, and is the standard for the majority of motors sold in the US.

What is B5 mounting?

B3 – Foot Mounted Motor. B5 – flange (‘D’ flange) The flange diameter is bigger than the motor frame diameter. The holes are not tapped. B5 flanges are available for all motor sizes.

What is B3 mounting in motor?

The standard IEC mounting position places the junction box on the top of the motor, known as the IM B3 mounting position in IEC frame (or F3 in NEMA frames). Below is a visual reference of typical electric motor mounting positions. Whether you’re an installer, engineer, or maintainer, this is a must -have reference.

Can you change motor mount from F1 to F2?

It really is manufacturer specific (what brand is it?). However, most 3 phase smaller motors (under 250 hp) are symmetrical so you can take the motor apart and flip the stator to get F2 mount. Remember that you flip the stator not the rotor – meaning the end bells stay with the rotor.

Which is the correct mounting position for an electric motor?

For electric motor mounting positions, NEMA and IEC set the standards. They are very similar but do have some slight differences. The standard mounting position is F1 by NEMA standards for industrial mounts. This position is where the junction/conduit box is located on the left side of the motor facing the output shaft.
