Mounting forms
There are several forms of mounting for electric motors. The form of mounting determines how the motor will be mounted on the installation. This is very important information that is not always listed on the nameplate.
Explanation of mounting forms
B3: motor fixed by legs
B5: large flange at the front of the motor, the holes are through
B14-1: middle flange at the front of the motor, the holes are threaded
B14-2: small flange at the front of the motor, the holes are threaded
According to photos below, it is possible to combine a foot motor with a flange.
Mounting positions
After determining the mounting form, the mounting position of the motor must also be chosen.
This indicates whether the motor comes mounted horizontally, vertically axis down or up, upside down, etc.
Motor sizes
Certain dimensions (axle, key, flange, fixing distance between feet, etc.) are 100% standardized. Other dimensions (length, height, width, etc.) are not standardized and are dimensioned according to the manufacture of the manufacturer.
It is therefore very important to validate the dimensions before ordering a new engine.
