Vibration Testing & Balancing Are Critical to Rebuilding Electric Motors

Vibration is a highly destructive force in rotating machinery. It can be caused by rotor unbalance, loose bearing fits, shaft shoulder runout, bearing housing mis-alignment, and shaft deflection.

In addition to shortening bearing and motor life, excessive vibration can be transmitted to the driven machine, negatively affecting machine performance and increasing operator fatigue.

Our rebuild process includes precision dynamic balancing of rotors and rotation components, but we recognize that balancing isn’t always enough. So during final run testing we measure the overall vibration of each motor to verify that it meets or exceeds the relevant DIN ISO, IEC, or JIS specification.

Vibration spectrums are recorded and archived for motors with especially high speed or low vibration requirements.

Endeavor Technologies also offers precision balancing for spindles, impellers/fans, rotors for built-in motors, and other components. If your part requires a special balancing arbor or fixture we can construct it.
