Force and kinematics of the rotor on magnetic bearing (MB) in the air or water are discussed during the start-up, on the basis of the new-generation maglev artificial heart pump. The response characteristics of electromagnetic actuator was researched during the start-up. Based on considering the conflict between the physical limits of existing MB power supply and start-up performance, the better controling parameters to solve it were determined under each medium. Its rationality is verified through the experiment.
