Abstract
Single-phase Induction Motors (SPIM) with Capacitor Start, are a sort of induction motor widely used in industry. Based on type of starting, single-phase induction motor (SPIM) is categorized as (1) Split phase, (2) Capacitor Start, (3) Shaded Pole, and (4) Repulsion Type. Today for disconnect 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 remove from the circuit. This is repeated for each startup. The centrifugal switch acts mechanically, so in over time it will be destroyed. Thus causing switch not working and the motor will be seriously affected. In this paper the centrifugal switch removed and smart devices using inductive proximity sensors (IPS) and magnetic field monitoring system (MFMS) is proposed. This system will be improved motor performance and efficiency. The simulation has been verified by Maxwell software. Result is shown at the end this document. It compared with previous approaches which show improvement.
