Summary: An improved current reconstruction method is proposed to enhance the performance of position sensorless control with a single current sensor at low speeds. High-frequency voltage is inserted to estimate the rotor position, and the phase current is compensated using an online adaptive one-step method to reconstruct time-aligned three-phase currents. The impact of the error between time-aligned reconstructed currents and full sensor sampling currents on sensorless control is analyzed. Experimental results demonstrate the feasibility of the proposed method for sensorless control of a permanent magnet synchronous motor.

Summary: This paper introduces a resolver offset calibration algorithm which can detect offset with high precision in a simple experimental environment. It is advantageous for large-capacity PMSMs that require substantial resources for setting up experimental environments. The algorithm, based on the PMSM voltage equation, is validated through simulation and experimental verification, showing that the calibrated offset error converges within 3 bits out of 12 bits resolution with minimal deviation.

Summary: This article introduces a general-purpose full-speed sensorless control scheme for IPMSMs using a QBEMF model for a universal control strategy. The QBEMF model acts as a self-demodulator at low speed to extract position information from high-frequency currents without digital filters. At high speed, the same QBEMF model can be used for position estimation, solving the conventional transition issue from low-speed to high-speed sensorless control.

Summary: There has been active research in fault diagnosis of permanent magnet synchronous motors (PMSMs), with a focus on motor current signature analysis (MCSA). However, both MCSA and vibration analysis are unable to distinguish the type of fault, leading to the proposal of a simple automated test method based on vibration measurement for identifying mass unbalance.

Summary: This article discusses the detection and repair of rotor cage damage in induction motors, as well as the factors that affect fault detection. Motor current signature analysis (MCSA) is the most widespread method for fault detection, but it has limitations and can result in false indications and failures to detect faults. Therefore, researchers propose a new test method based on time-frequency analysis of the airgap flux, which has been verified to provide reliable detection of rotor faults.
