The primary difference between motor frame 449T and 449TS lies in their design and application. The "S" in 449TS typically indicates a special feature or modification, such as enhanced cooling or a specific mounting configuration. Additionally, the 449TS may be optimized for certain operational conditions or efficiency requirements, whereas the 449T is a standard frame without those enhancements. Always refer to the manufacturer's specifications for detailed differences.
