Abstract
The utility relates to a control device of a electric magnetic chuck for automatic magnetization and degaussing control. The utility is characterized in that the input end of the power supply, the voltage regulating circuit connects to the input end of the rectifier circuit in series, thus forming a loop and further outputting a direct current supply with an adjustable voltage. The output end of the voltage regulating circuit and the polarity conversion circuit switch the polarity of the output direct current supply under the control of the control circuit. The utility is of a simple structure and low cost, works stably, needs only a short time for degaussing, and has a preferable degaussing effect.
