| Abstract: | An equipment of non-contact electromagnetic loading in high speed motorized spindle is designed. Thisequipment is mainly composed by DC electromagnet, rectifying circuit, three-level PWM modulate switching power amplifier and loading disc. The electromagnetic field of DC electromagnet is interaction with loading disc. Steady and adjustable electromagnetic force is produced on loading disc. Thus non-contact electromagnetic loading is realized. This method is used not only torque loaded but also radial force loaded in the experiment of high speed motorized spindle＇s dynamic performance. Problems that torque is hard loaded and radial force is unable loaded to high speed motorized spindle are solved. |
