Abstract :
Electrical spindle is one of the key components of high speed and high-precision machine tools. Engineering ceramic is the ideal material for high-speed and high precision electrical spindle due to perfect characteristics of light weight, wear resistance, high temperature, high strength, and so on. A test system is developed to measure no-load current, temperature rising, vibration and noise of the ceramic electrical spindle in this paper. The effects of rotating speed and air-gap between the rotator and stator on these characteristic parameters of the electrical spindle are analyzed. Experimental results show that, with the increase of rotating speed, no-load current almost keeps constant, and temperature, vibration and noise increase; no-load current increase with the increase of air-gap, but the temperature, vibration and noise decrease. These results are very helpful to the structure optimization and application of the ceramic electrical spindle.
