To get a better electromagnetic performance of an axial flux permanent magnet brushless DC motor (AFPMBLDC), AFPMBLDC with arc-shaped magnets and its multi-objective optimization design are researched. Firstly, the main parameters proposed, initial designs carried out according to given requirements. Furthermore, pole arc coefficient, thickness, radius, air-gap length selected as factors. Then,...

A wavelet transform on the negative half real axis is developed using an average-interpolation scheme. This transform is redundant and can be used to perform causal wavelet processing, such as on-line signal denoising, without delay. Nonetheless, in practice some boundary effects occur and thus a small amount of delay is required to reduce them. The effect of this delay is studied using a numer...

This paper describes the experimental study carried out on a Permanent Magnet Brushless DC (PMBLDC) Motor drive coupled to a pump load powered by photovoltaic (PV) array I for water pumping system. A simple low cost prototype controller has been designed and developed without current and position sensors which reduces drastically the overall cost of the drive system. This controller is used to ...

This paper presents to estimating studies of the torque data Electric Vehicle (EV) motor using Adaptive-Network Based Fuzzy Inference Systems (ANFIS). The real-time set Outer-Rotor Permanent Magnet Brushless DC (ORPMBLDC) which was designed and manufactured for in ultra-light EV, used these estimation process. current, power speed parameters are defined as input variables, parameter output vari...

An experimental investigation is conducted to determine the behaviour of brushless PM synchronous machine parameters in the high speed flux weakening operating range. Real-time operating characteristics are determined for two commercially available 4 N·m interior PM synchronous machines. Special computer assisted measuring techniques are employed using an experimental vector controlled drive, c...

In this paper, a buck half-bridge DC-DC converter is used as a single-stage power factor correction (PFC) converter for feeding a voltage source inverter (VSI) based permanent magnet brushless DC motor (PMBLDCM) drive. The front end of this PFC converter is a diode bridge rectifier (DBR) fed from single-phase AC mains. The PMBLDCM is used to drive a compressor load of an air conditioner through...

Electric machines play an important role in modern energy conversion systems. This paper presents a novel brushless fault-tolerant flux-modulated memory (FTFM) machine, which incorporates the merits of a flux-modulated permanent magnet machine and multi-phase memory machine and is very suitable for applications that require wide speed ranges of constant-power operation. Due to the magnetic modu...
