Explanation
In high-speed universal motors, ensuring the rotor is properly balanced is crucial to prevent excessive vibration and mechanical stress, which can lead to premature failure. While factors like axial clearance, air gap, and insulation are important, rotor balancing demands the most attention at high speeds.
