Abstract	Based on the type of starting, single-phase induction motor (SPIM) is categorized as (1) Split phase, (2) Capacitor Start, (3) Shaded Pole, and (4) Repulsion Type. The single-phase induction motors (SPIM) with Capacitor Start, are a sort of induction motors widely used in industry. Today for disconnecting the auxiliary winding and start capacitor of SPIM the centrifugal switch is used. Also when the motor has reached 75% of normal speed by some contacts, switching is done and auxiliary winding and start capacitor is removed from the circuit. This is repeated for each startup. The centrifugal switch acts mechanically, so over time it will be destroyed, thus causing the switch not to work and the motor will be seriously affected. In this paper the centrifugal switch is removed and smart devices using inductive proximity sensors (IPS) and magnetic field monitoring system (MFMS) are proposed. This system will improve motor performance and efficiency. The simulation has been verified by Maxwell software. Result is shown at the end of this document. It is compared with previous approaches which show improvement.
