IEEE Transactions on Industry Applications, 2001 The performance of a voltage-controlled large induction motor soft starter has been improved, resulting in nearly perfect current and torque profiles. The performance analysis of the soft-starter motor-load combination has been carried out in the dynamic state using a hybrid induction machine model which takes account of disconnected two-phase and ...

A new simplified sensorless direct stator field-oriented control of induction motor drives
Frontiers in Energy Research, 2022 A field-orientation scheme is a typical control technique of induction motors to obtain sophisticated performance. The stator field-oriented control is less sensitive to parameter variations than the rotor field-oriented control.

Dual-Mode Brushless Wound Rotor Synchronous Machine for High Starting Torque
IEEE Access, 2022 This paper proposes a dual-mode brushless wound rotor synchronous machine (DBL-WRSM) for high starting torque. The proposed DBL-WRSM consists of two modes: induction and brushless (BL)-synchronous modes.

Photoelastic Torque Sensor Development for Measurement of Starting Torque of a DC Micromotor
Procedia Engineering, 2016 Abstract This paper describes the development and the calibration of a photoelastic torque sensor and it presents the measurement of the starting torque of a DC micromotor as a function of the rotor angle. Due to the relatively small torque ( [1] and the results were compared to each other.
