1results about How to "Improve control characteristics" patented technology

This invention discloses an electromagnetic chuck control device and a control method for the electromagnetic chuck control device. The electromagnetic chuck control device includes: a command input module, a main controller, a phase-shift trigger, a thyristor module, an electromagnetic chuck, and a sampling feedback module. The command input module is connected to the main controller and is used to transmit external commands to the main controller. The sampling feedback module is connected between the electromagnetic chuck and the main controller and is used to sample the current and voltage of the electromagnetic chuck and feed them back to the main controller. The phase-shift trigger is connected between the main controller and the thyristor module and is used to trigger the thyristor module according to the trigger signal sent by the main controller. The thyristor module is connected to the electromagnetic chuck and is used to rectify AC voltage into DC voltage and control the electromagnetic chuck. This invention can improve the adjustment accuracy and working efficiency of the electromagnetic chuck's magnetic force and enhance the intelligence level of the electromagnetic chuck device.
