Information was not provided.Approximate age of device - the motor is not a single use device.The approximate age of the device is 4 years, 1 month, calculated from the date of manufacture.The returned centrimag motor was evaluated and tested and it was confirmed that the returned motor was defective.When the motor was connected to a test centrimag 2nd gen console the console displayed a "motor disconnected:m2" message, even after numerous attempts.The motor was never detected by the console.As a result, the report of vibrations and speed changes could not be confirmed.Continuity testing of the motor cable revealed an intermittent open connection in the input current bearing phase b2 (ib2+ line) and the output current bearing phase b2 (ib2-).When the motor cable was manipulated near the motor end bend relief the resistance value would change, indicating that the issue was a result of conductor breakdown in the motor cable.Although the root cause of this breakdown could not be conclusively determined, it appeared to be a result of repetitive bending or twisting of the motor cable during use.A review of the device history records revealed the device met applicable specifications.No further information was provided.The manufacturer is closing the file on this event.
