Where are the two bearings of a typical electric motor mounted?

Explanation:
Bearings are placed inside the motor housing on the ends of the rotor shaft. This internal mounting provides proper radial and axial support, keeps the shaft precisely aligned, and protects the lubricants and seals from dirt and moisture. External mounting would expose the bearings to more wear and contamination, and the drive pulley attaches to the shaft outside that bearing region. So, the two bearings are mounted internally.
