Application of the Solid-State Relay Circuit in the Motor Positive and Reversion in the Bar Machine

This article describes the application of solid-state relay of the motor positive electrical circuit, based on this designed the bar control system, which has high practicability. The main use of keys, solid-state relay, three-phase asynchronous motor and the signal processing circuit, compared with the previous way of electromagnetic relay, enables it to be small and simple and to have, the advantages of stable operation.
