In this article, the parameter identification of a brushless DC motor (BLDC) is presented. The approach here presented based on direct considering three-phase line-to-line voltage electromagnetic torque as function electric currents and rotor speed. estimation divided into two stages. First, electrical parameters are estimated by well-known no-load tests. Consequently, mechanical performed usin...

In the existing situation, DC motor calls for a frequent upkeep and need mechanical commutator brushes, that are concern to put on tear. prevailing case Brushless Direct Current extensively used in some of industries because its low cost, noise less operation, high speed torque characteristics, Speed controlling is very essential. Hence BLDC preferred control speed. The manipulate could be esse...

Light urban electric vehicles are an important target, both for the researchers and manufacturers. Concerning the motor’s choice, more ways are investigated, but the most important is that as compact as possible solutions have to be used. In the top of the preferences, the permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC) are situated. These are preferred thanks to their...

Angle of rotation is a key parameter in motor fault diagnosis under varying speed conditions, and usually measured by an optical encoder. However, the use encoders intrusive many scenarios its signal difficult to access due technical or commercial reasons. In this study, novel angle measurement method based on stray flux analysis proposed applied bearing brushless direct-current (BLDC) motors. ...

What I cannot create, I do not understand. Abstract T he auto-commutated permanent magnet synchronous motors, or brushless DC motors (BLDC), are more and more used in many different industrial low power (< 1 kW) applications. BLDC motors have the phase coils on the stator and the permanent magnet(s) on the rotor. Besides many advantages provided by this configuration , a drawback is that the po...

The slot opening displacement technique presented in this article to reduce BLDC motors suitable electric two-wheeler Methods. Double rotor single stator configuration motor most such vehicular Initially double 250 W, 150 rpm designed ...

This paper uses a new position sensor less drive for brushless DC (BLDC) motors. In conventional sensor less control methods such as the back-EMF detection method, the performance is high only at a high speed range due to the fact that the magnitude of the back-EMF is dependent on the rotor speed. A solution is derived that estimates the rotor position by using an unknown input observer over a ...

The main advantage of the recurrent cerebellar model articulation controller (RCMAC) is its rapid learning rate compared to other neural networks. This paper proposes an adaptive RCMAC control system for a brushless DC (BLDC) motor. The proposed control scheme is composed of an RCMAC controller and a robust compensator. The RCMAC controller is used to mimic an ideal controller, and the robust c...
