Abstract	This paper introduces two different novel designs of interior permanent-magnet synchronous machines with concentrated windings, which are attractive to a self-sensing control system. The new machines have some advantages: lower subharmonics of air-gap flux density and magnetomotive force and lower machine losses, including eddy current losses. The machines have been adapted for self-sensing applications by using a high-frequency (HF) injection method. The main machine parameters affecting the estimation accuracy are analyzed such as fundamental frequency saliencies, cross saturation, HF inductance, HF resistance, and harmonic distortion due to multisaliencies. The experimental results verify that the novel machines can reach very high performance with good self-sensing properties regarding the accuracy of the estimated position/speed of electric drives even without the multisaliency decoupling compensation method.
