Optimal operation of the rotating transformer brushless excitation of synchronous machine
2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004The brushless excitation of synchronous machines is an attractive solution for wound rotor machines, since no slip rings are necessary. The paper investigates the rotating transformer method, where the excitation machine is a wound rotor induction machine supplied by an excitation converter.

Operating Condition Generalization Network for Fault Diagnosis of Brushless DC Motors
IEEE Transactions on Industrial ElectronicsInternational audience ; Existing fault diagnosis methods for brushless dc motors (BLDCMs) encounter problems of limited adaptability in terms ofmultiple faults, multiple motor types, and cross-operating conditions. Therefore, we propose an operating condition generalization network (OCGN) based on the recently proposed domain-invariant feature ...

A brushless generation system for microgrid operation utilizing dual stator induction generator
2014 IEEE 23rd International Symposium on Industrial Electronics (ISIE), 2014Modern micro-grid needs to integrate all possible and economically attractive renewable energy resources. In many cases these generations are not smooth in nature and are situated in remote locations where regular maintenance is difficult. This paper proposes a brushless generation system using a dual stator winding induction generator (DSWIG).

Hall-sensor signals filtering for improved operation of brushless DC motors
2011 IEEE International Symposium on Industrial Electronics, 2011Brushless dc (BLDC) motors controlled by Hall-effect sensors are becoming widely available and used in a wide variety of applications. Such motors have been extensively researched in the literature under a common assumption that the Hall sensors are ideally placed 120 electrical degrees apart. However, sensor positioning may be quite inaccurate in low-

Comparison of operating modes for a brushless doubly fed reluctance motor drive
2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017This paper investigates a novel two-converters based operation of a Brushless Doubly Fed Reluctance Machine (BDFRM). The BDFRM has a ducted rotor, and the stator is wound with two distributed windings which are fed from two separate power converters. Operation theory with frequency sharing between the two windings is introduced and corresponding FEA ...

Sensorless operation of brushless DC motor drive designed for air conditioners
2017 International Conference on Innovations in Electrical, Electronics, Instrumentation and Media Technology (ICEEIMT), 2017This paper presents the simulation for sensorless operation of BLDC motor drive with speed control, designed for Air conditioners. As the motor starts to rotate back EMF is obtained from the motor terminals using a voltage divider along with a low pass filter. Control pulses for inverter are generated based on the zero crossing of back EMF. The results

Design criteria for brushless dc motors for high-speed sensorless operation
International Journal of Applied Electromagnetics and Mechanics, 2001A design criteria for brushless dc motors for high-speed sensorless operation is described. It is shown that motors can be designed such that the free-wheeling diodes in the power electronic drive have a low conduction angle, while exhibiting high efficiency.
