Regarding the thermal behavior of the main spindle driving system with the electromagnetic disk clutch, experimental investigations have been carried out in both the rotational and nonrotational conditions, in which the visualization of the temperature distribution has also been employed. This paper presents some interesting observations obtained from such experiments, and gives very useful guidelines to reduce the thermal behavior in designing such a driving system. For instance, the results show that the frictional heat of the clutch bearing strongly affects the thermal behavior of the friction disk, driven shaft, magnetic body and that the slip characteristic of the clutch has considerable effects on the thermal behavior of the system. In addition, this paper suggests that the self-ventilation using the rotational friction disk is the most effective in reducing the thermal influence on the system.
