<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>

“…Many proposals to improve the SPIM performance are based in the use of an electronically switched series capacitor in the auxiliary winding, which can be controlled to improve the machine performance at different operating conditions [1], [2], [3], [4]. Considering the use of variable speed drives, the most of the control techniques for the SPIM drive are based on the use of constant V/F relation, phasor, or on vectorial control with field orientation, usually utilizing appropriate transformations in order to eliminate the asymmetry of the stator windings [6], [5], [7], [8], [9], [10], [11], [12], [13], [14]. Sensorless techniques is the more reasonable option for the control of fractional and low cost SPIM applications, since the small size and low cost of this motor does not justify the use of speed sensors due to reduction of reliability and increase of complexity, cost, difficulties, weight, size, and electrical susceptibility.…”

The single-phase induction motor (SPIM) is one of the electrical machines more used in the World, and can be found in several fractional and sub-fractional horsepower applications in houses, offices, shoppings, farms, and industries. The introduction of more sophisticated applications has required the use of variable speed drives for SPIM, where the adoption of sensorless techniques is the more reasonable option for speed control due to the low cost of this electrical machine. A proposal for sensorless variable speed SPIM drive based on direct rotor field orientation techniques is presented in this paper. None transformation is used in order to eliminate the asymmetry of the stator windings of the SPIM. The rotor speed is estimated from an flux observer, which is based on two independent linear feedback control systems. The speed and flux estimatives are used in two control loop based on PID regulators, which determine the voltages to be applied to the SPIM windings by a three-legs VSI inverter. Using computer simulations, two situations are considered in order to demonstrate the satisfactory performance of the proposed sensorless speed control for SPIM drives: variations on rotor speed reference and the application of mechanical load
