This paper studies of bearing load’ s effect factors in solid type permanent-magnet machine, proposes the load calculation method, analyzes and calculates by the example of the TYCKK3554-4 (6kV 250 kW). The main factors affecting the bearing load are unilateral magnetic force,eccentricity of the rotor rotating inertial centrifugal force,gravity and load unbalance force. This study provides the basis for the selection of motor bearing,and has great significance to improve the reliability and service life of motor.
