IM mounting design determines how the motor is attached to the mechanism. When replacing, this is critical: an engine with an unsuitable design simply cannot be installed. Let's look at the codes.
What is IM
IM (International Mounting) is a standard designation for the method of engine mounting. It indicates whether the motor is foot-mounted, flanged or combined, as well as the position of the shaft.
The most common designs
| Code | Description |
|---|---|
| IM B3 (IM1001) | Foot-mounted, shaft horizontal |
| IM B5 (IM3001) | Flange mount |
| IM B35 (IM2001) | Foot mounted + flange |
| IM B14 | Small flange |
| IM V1 | Vertical shaft down |
How to choose when replacing
The mounting design of the new engine must match the design of the one being replaced - otherwise it will not fit into place. Check the presence of feet, flange and shaft position. The combined version (B35) is more universal - it can be installed both on feet and on a flange.
The installation design is checked together with overall mounting dimensions when motor selection. If it is impossible to find an exact analogue, consider repair.
