Notes:
Motorized spindle is high speed machining unit combined with hidden motor andmachine tools axis, which has advantages of high speed, stepless transmission, zero transmissionchain, and is applied in machine center widely. Key technologies are combined together inmotorized spindle designing, such as high speed motor, bearing, manufacturing and assemblage. Itis strict in assembling to guarantee rotating precision and dynamic balance and is different fromcommon machine tools designing due to characters of high speed and hidden motor. Hydrostaticbearings have advantages of high carrying capacity, lower friction, and better holding precision, theheat problem is extrusive, but the future of hydrostatic motorized spindle is considerable. Modaland thermal performance analyses are necessary for motorized spindle designing. With modalanalysis, inherent frequencies are confirmed, which could be of help to avoid sympathetic vibrationin machining. It provides evidence for designing cooling system of thermal performance analysis
