MOTOR ASSEMBLY AND METHOD OF MANUFACTURING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17808462 titled 'MOTOR ASSEMBLY AND METHOD OF MANUFACTURING THE SAME

Simplified Explanation

The abstract describes a method of manufacturing a motor assembly that includes a motor and an impeller coupled to a rotation shaft of the motor. The method involves the following steps:

• Placing a plurality of balls in a ring-shaped groove on the surface of the impeller.
• Rotating the impeller at a speed higher than its resonant rotation speed.
• This rotation causes the balls to move to a compensation position, which helps to compensate for any eccentricity in the motor assembly.
• Finally, the balls are fixed in the compensation position within the groove.

Potential applications of this technology:

• This method can be used in the manufacturing of various motor assemblies, such as those used in fans, pumps, or other rotating equipment.
• It can be particularly useful in applications where precision and balance are crucial, such as in high-speed machinery or precision instruments.

Problems solved by this technology:

• Eccentricity in motor assemblies can lead to vibrations, noise, and reduced performance.
• This method helps to compensate for any eccentricity, ensuring smoother operation and improved performance of the motor assembly.

Benefits of this technology:

• By using this method, manufacturers can achieve better balance and reduce vibrations in motor assemblies.
• It allows for more precise and efficient operation of the motor assembly, leading to improved performance and longevity.
• The method is relatively simple and can be easily incorporated into existing manufacturing processes.

Original Abstract Submitted

A method of manufacturing a motor assembly comprising a motor and an impeller coupled to a rotation shaft of the motor, the method includes disposing a plurality of balls in a ring-shaped groove formed in a surface of the impeller; rotating the impeller at a speed greater than a resonant rotation speed to move the balls to a compensation position for compensating for an eccentricity in the motor assembly; and fixing the balls at the compensation position in the groove.
