Hybrid Intelligent Method of Identifying Stator Resistance of Motorized Spindle
Aiming at the problem that changes of nonlinear dynamic resistance of stator affect the performance of speed sensorless vector control system, a hybrid computing intelligence approach is used in the identification of stator resistance of motorized spindle. The partial least squares (PLS) regression is combined with neural network to solve the problem of few samples and multi-correlation of vari...
متن کاملComprehensive Measurement and Evaluation System of High-speed Motorized Spindle
Original scientific paper Reducing the manufacturing time is the trend of high precision manufacturing, and the precision of a work-piece is very important for the manufacturing industry. The high-speed motorized spindle is the most critical part and becoming more widely used in the machine tool at present, and its precision may affect the overall performance of high-speed cutting. Most of the ...
متن کاملRobustness of Improving Active Maglev Motorized Spindle Equilibrium Position
The equilibrium position of active maglev motorized spindle had great influence on the industrial processing accuracy, in order to improve the performance of active maglev motorized spindle and processing accuracy, a new control method and control device of active maglev was put forward based on H∞ mixed sensitivity. Firstly, a mathematical model was established among the electromagnetic force ...
متن کاملAnalytical Modeling of Thermal Resistance in Bolted Joints
An analytical approximate solution is developed for predicting the thermal resistance of bolted joints between two square plates . of the same material but different thicknesses. The plates are assumed to have perfectly flat and smooth surfaces, and they are joined by a bolted connection at the center of the square, forming a concentric annular contact region at the interface. The entire surfac...
متن کاملPower Matching Based
To overcome the imbalance between spindle heat generation and dissipation caused 11 by existed spindle cooling strategies, this paper develops a power matching based cooling 12 strategy for motorized spindle unit. Firstly, heat generation, conduction and dissipation are 13 considered for the modeling of spindle structural heat exchange. This modeling methodology 14 conveys that an operating mot...
