“…According to the signal of the step-down transformer and the step-up transformer, the base condition of the motor is determined whether it is starting, running with load or running without a load. The zero setting circuit detects the zero crossing point of the supply voltage and thus helps the control circuit to adjust the ignition angles of the electronic switch [8]- [11].…”

<span lang="EN-US">Single-phase split induction motors consist of an auxiliary coil, a main winding and a centrifugal switch that separates the auxiliary coil. The starting torque of this motor is not large, and a resistance has to be added with the additional coil to increase the starting torque. Also, a mechanical centrifugal switch is used to disconnect the auxiliary coil. The motor also has another drawback that it has a constant speed. The aim of this research is to replace the added resistance with a current transformer that has a predetermined resistance and connected in series with the auxiliary coil such that it results in a maximum starting torque. In addition, it sends a signal to a control circuit that disconnect/connect the auxiliary coil through an electronic switch connected in series with the auxiliary coil. The connection/disconnection of the switch depends on the motor current not the motor speed to overcome the problem of switch false triggering due to motor overloading. The new technique increases the overall efficiency of the motor. MATLAB is used to simulate the system and verify the mathematical model.</span>

“…The two coils are different in the number of coils, the diameter of the wire and the distribution of the wires, and the starting capacitor comes out after 75% of the motor speed, and the current of the auxiliary coils is very little and has no real effect on the rotation of the motor. In the slotted sewers, the starting coils are completely separated after 75% of the engine speed [6]- [13].…”

“…This is so that the current in the two coils has a role in operating the motor, and an internal adjustment can be made in the motor's coils by making the coils equal in terms of the number of coils and wire diameter, and thus we get an equal current in the coils and between them an angle of 90 degrees. The mmfs generated by the currents of the two coils are balanced and the rotor mmf disappears backwards [6]- [13].…”

<span lang="EN-US">Single phase induction motor (SPIM) has zero torque, this motor has many types and the main objective is to find the starting torque of the motor. This is done by providing auxiliary coils that are mechanically separated or weakened after 75% of the engine speed. The real problem here is that these auxiliary windings occupy a third of the iron core of the motor, and when they are separated or weakened, the capacity of the iron core is not fully used and the main windings must withstand the rated load current alone which shortens the life of the motor and reduces the hours of continuous operation of the motor. In this paper, a single-phase motor is fed from a single-phase power source and again from a two-phase power source, so that the auxiliary coils are not separated after 75% of the motor's speed and have a continuous role in the motor's operation. The torque and current flow in the motor are compared in both cases. Due to the rarity of the two-phase power supply in nominal uses, it can be supplied by a full bridge inverter. This comparison was provided by steady-state analysis and the results of MATLAB Simulink. </span>
