Recently, performance improvement and speed control of Single-Phase Induction Motors (SPIMs) have been paid attention. These aims is required the machine speed. In this paper, a method is proposed to estimate the SPIMs speed, and then, its application in torque optimization of the machine is investigated. For this purpose, the motor speed is obtained in terms of the motor parameters and stator flux linkage components by use of the SPIMs equations in stationary reference frame. By obtaining the flux linkage from motor windings voltages and currents, the motor speed is estimated desirably. Then the estimated speed is used to increase the average torque, to decrease the pulsation torque and to optimize the motor torque. After that, the simulation results in condition of using the real speed is compared with the estimated speed one. The low simulation error proves the validity of the proposed method
