Research on Operating Performance for Hybrid Rotor Synchronous Motor
AbstractThis paper with an open-loop V/f control mode of inverter supply, searched for the causes of the oscillation using small signal analysison the axially-laminated anisotropic (ALA) rotor and hybrid rotor (ALA-SPM two-part) motor, and analyzed operating performance of themotors with inertial damper on the same shaft. Results show that the negative electromagnet damping coefficient can be the key point toresult in the oscillation; the electromagnet damping coefficient can increase with the increasing new variable k, the fraction length of SPMpart, the maximum load of the motors and the stability can be improved. The stability of the system and the dynamic performance can bebetter with reasonable viscous damping coefficient of inertial damper, the motors can adequately develop their output torque capability,and improve operating performance.
