The embodiment of the invention discloses a gate machine core, and a gate machine provided with the gate machine core can be applied to more application sites and is convenient to transport. According to a method of the gate machine core, a power subsystem comprises a driving motor, and a gate subsystem comprises an elastic energy storage device and an electromagnetic device; the elastic energy storage device comprises an elastic part which acts on a barrier part, and the electromagnetic device comprises an electromagnet; when the electromagnet is electrified, the electromagnetic device is connected, and the power subsystem controls the action of the barrier part through the electromagnetic device and synchronously enables the elastic part to deform for energy storage; and when the electromagnet is powered off, the electromagnetic device is disconnected, and the barrier part acts under the control of the elastic part. Accordingly, the driving motor and the elastic part jointly act to enable the barrier part of the gate machine to be opened and closed, and due to the fact that the elastic part is easy to mount and transport and has no influence on using environments, the gate machine provided with the elastic part is easy to transport and can be applied to more application sites.
