  Single phase Direct online starter  ( DOL) is a device consist of main contactor, protective devices and overload relay which is used for motor starting operations. It is used for low rating usually below 5HP motors.  direct online starter method of motor starting, the motor stator windings is directly connected to the main supply where the DOL protect the motor circuit from high inrush current which may damage the overall circuit as the initial current is much more higher than the full rated current. Why do we need DOL starter? At startup, the induction motor consumes a significant quantity of current. The motor windings may sustain damage from this beginning current. We employ many methods to lower the beginning current employing Motor Starters (such as star delta or DOL starters) in order to prevent any harm. The motor ratings and the load attached to the motor determine these methods. In addition, the motor starter guards against over-current and overloading. NOTE B...

What is Stator? A stator is the stationary part of an electric motor or generator, consisting of coils or windings mounted on an iron core, designed to create a magnetic field when electric current flows through it. Simply you can say the house of the motor which inside contains Winding slots, bearing, rotor and fan. Learn More Stator Core : In the past, the stator core has changed from solid iron cores to electrical steel laminated sheets, which greatly minimizes energy losses from eddy currents. Carefully packed together, these laminations provide a core that supports the windings and improves the magnetic flux efficiency. Modern stator cores are now more dependable and efficient because to the use of cutting-edge materials and production processes. High-performance electric cars, for instance, depend on these upgraded cores to optimize power production, output, and efficiency . Windings:  The windings, typically made from insulated copper wires or aluminum wires, are crucial for...

               A single-phase induction motor is composed of a single-phase winding located on the  Stator and a cage windings on the rotor. When a single-phase power supply is applied to the stator winding, it generates a pulsating magnetic field. Due to inertia, the rotor remains stationary in this pulsating field.The structure of the single phase induction motor determines that the reverse rotation is generally completed by hardware.   Internal wiring structure of single-phase induction motor           Why there is a capacitor?   1.In the original setup, both the main coil and the auxiliary coil receive power simultaneously, creating equal electromagnetic forces that oppose each other, preventing the rotor from turning.  2 .  To make the magnetic field force rotate, it can be achieved by passing alternating currents of different phase sequencing the main coil and the auxiliary coil.
