Position Sensorless Control Method at Zero-Speed Region for Permanent Magnet Synchronous Motors Using the Neutral Point Voltage of Stator Windings
Autor: Ryoichi Takahata, Yoshitaka Iwaji, Shigehisa Aoyagi, Takahiro Suzuki
Publikováno v: IEEE Transactions on Industry Applications. 52:4020-4028
A new sensorless control method that uses the neutral point voltage from stator windings is proposed. Each inductance of the three phase coils of the permanent magnet synchronous motor (PMSM) is slightly affected by the rotor magnet flux. As a result

Autor: Takafumi Hara, Ryoichi Takahata, Yoshitaka Sugiyama, Y. Iwaji, Shigehisa Aoyagi, Toshiyuki Ajima
Publikováno v: 2018 XIII International Conference on Electrical Machines (ICEM).
A mathematical model is described for predicting fluctuation in the neutral point voltage from stator windings to drive a permanent magnet synchronous motor (PMSM) in the zero speed-region. The model is derived under the assumption of small motor cur

Minimum Current Start-Up Method by Combined Use of Two Position-Sensorless Controls
Autor: Takahiro Suzuki, Yuichi Shimizu, Yoshitaka Iwaji, Ryoichi Takahata, Shigehisa Aoyagi
Publikováno v: IEEE Transactions on Industry Applications. 51:3086-3093
A start-up method for reducing the start-up current of a permanent-magnet synchronous motor (PMSM) is proposed. Minimum current start-up is achieved by combining two position-sensorless control methods that require no harmonic injection. Position-sen

A Simplified Sensorless Vector Control Based on Average DC Bus Current for Fan Motor
Autor: Daisuke Maeda, Shigehisa Aoyagi, Kazuaki Tobari, Satoshi Sumita
Publikováno v: IEEJ Transactions on Industry Applications. 130:1233-1240
This paper describes a simplified sensorless vector control based on the average DC bus current for PMSM. This method can be used to design a drive control system at a relatively low cost because the microcontroller does not require a precise timer a

A New PWM Modifying Technique for Reconstructing Three-phase Currents from DC Bus Current
Autor: Kiyoshi Sakamoto, Kazuaki Tobari, Yoshitaka Iwaji, Shigehisa Aoyagi
Publikováno v: IEEJ Transactions on Industry Applications. 130:401-406
Vector control is used to drive a DC brushless motor and generally needs current information. DC bus current detection is often adopted as a low cost method for reconstructing three-phase currents. PWM modifying techniques increase the DC pulse durat
