Rotating motor-armatures, supported on magnetic fields without any contact between solid surfaces and spun at speeds of 3400 to 6000 rpm are reported. This type of bearing requires an active servo in at least one dimension, and this servo is often found to couple rather stubbornly to flexure vibrations of mechanical elements of the system. Ways of eliminating this vibration lock-on will be important future objectives of the investigation. Author
