Little steel ball electromagnetic launch system

The utility model discloses a little steel ball electromagnetic launch system, this system include bobble, track, accelerating coil, sensor, charging circuit, discharge circuit and control circuit, bobble, sensor and accelerating coil are placed on the track, control circuit and charging circuit are connected, the discharge circuit is connected with discharge circuit, control circuit and accelerating coil respectively, control system is connected with the accelerating coil. Accelerating coil and discharge circuit are two sets of, charging circuit and control circuit respectively with the two sets of accelerating coils and the circuit connection that discharges. The accelerating coil adopts the enameled wire coiling, 480 circles, and the internal resistance is 10 ohm, and the interval of two coils is 44cm. The bobble adopts the pombe of the real core of iron, diameter 2cm. The silicon controlled rectifier connection of discharge circuit is used for the high speed relay who drives the silicon controlled rectifier to drive. This system has the beneficial effect who raises speed in the twinkling of an eye of accurate range, changeable multistage range and transmission.
