The invention relates to a universal wheel with an electromagnetic brake system. The universal wheel with the electromagnetic brake system comprises a holder and wheels which are arranged on the holder and are provided with wheel holes, and is characterized by also comprising brake arms, reset springs, a dowel bar, a hollow shaft and an electromagnet; the brake arms are movably arranged in the holder and are provided with oblique planes and heads, and the heads of the brake arms are aligned with the wheel holes of the wheels; the reset springs are connected to one ends of the brake arms and the holder; the dowel bar is movably connected to the holder, one end of the dowel bar is provided with a protrusion which is abutted against the oblique planes of the brake arms; the hollow shaft is arranged on the holder and the dowel bar moves in the hollow shaft; and the electromagnet is provided with a shaft core which is connected to the dowel bar, and the dowel bar is controlled to move by the electromagnet through the shaft core. By adopting the universal wheel with the electromagnetic brake system, braking or removal of braking can be realized by controlling the electromagnet only, and less physical power is consumed.
