An iron-type single-disc linear motor coil switching means and method for moving

One kind of actuating device and method for a single disc iron linear motor coil switching, said switching means comprising a coil disc and disc drive, there is arranged a coil electrode is arranged on the drive disc drive coil electrode disc. Coil array coil electrodes are connected by wires to the coil, the drive electrodes are connected by wires to the driver. Disk drive coil and the disc with the movement of the magnet array relative rotation about the shaft, the coil electrode making contact with the separation of the drive electrode, thereby achieving the drivers of the array of coils different coils of the power supply. The present invention achieves an iron linear motor coil of each phase is shifted individually, reducing heat generation and reducing the number of drives, simple structure, no complicated control, to solve the leakage current and issues an electronic switching time delay.
