Balancing of a Rotor with Active Magnetic Bearing System: Comparison of One-and Two-Plane Balancing Procedures
Vuojolainen, Jouni; Jastrzebski, Rafal; Pyrhönen, Olli (IEEE, 01.11.2018)Rotor balancing is a procedure used to reduce the unbalance vibration of rotating machinery. Unbalance vibration creates forces to the bearings and causes harmful effects such as reducing their lifespan. Unbalance is caused ... -
