- Mounting Information
- WEG multivoltage aluminium frame motors with removable base were specially designed to meet market requirements in reference to mounting flexibility once they allow all mounting positions.
The foot mounting system offers great flexibility and it is quite simple allowing change on the mounting configuration without requiring any machining or modification on the motor feet. Motor terminal box can also be rotated at 90 degrees allowing motor leads to be connected on any motor side.
Besides that, these motors are fully interchangeable with the existing cast iron frame motors. These multivoltage aluminium frame motors are available in frame sizes 63, 71, 80, 90S/L, 100L, 112M, 132S and 132M.
