This paper presents a novel Brain Emotional Learning Based Intelligent Controller (BELBIC) for controlling some of the parameters, such as speed, torque, quadrature and direct axis current and voltage of an Interior Permanent Magnet Synchronous Motor (IPMSM). PI controllers are widely used as speed controllers in industries. IPMSMs are characterized as complex, highly non-linear and time-varyin...

Although many PMSMs are used as the driving source for electric vehicle motor drive systems, there is still a gap compared with power density index in DOE roadmap. Considering that occupies large space system, it of great significance system to increase and thus reach index. This article starts electrical machine basic design theory finds influence factors. Guided by considering driver influenc...

In traditional motor drive system, large volume electrolytic capacitors are utilized to buffer energy and stabilize the dc-link voltage. However, these affect reliability of drives narrow conduction angle diode-rectifier. As a result, grid side current is distorted power factor deteriorated. order settle issues, small can replace capacitors. this paper, torque control method with voltage feed-f...

This paper proposes a NCPM (Nano-composite coated permanent magnets)-based IPMSM (Interior Permanent Magnet Synchronous Motor) electric drive system, especially applicable for vehicles (EV). For an EV, increase in the “T/A (torque per ampere)” condition is highly recommended, as it directly affects maximum distance run by EV on single charge. Due to NCPM, substantial magnetic flux intensity, re...

When the interior permanent magnet synchronous motor (IPMSM) is running, there are abundant harmonics in stator current. In order to achieve suppression of current harmonics, harmonic extraction method and controller studied this paper. Firstly, a simple accurate for extracting proposed by means multiple rotating frame transformation (MSRFT). Secondly, an improved deadbeat predictive control (I...

Abstract Permanent magnet synchronous motors (PMSMs) have many advantages attributed to the structure of permanent magnet, which connects influences each type fault. However, diagnostic methods are not capable monitoring multitype faults with one index or method, due closed-loop control non-stationarity. There a few based on convolutional neural networks (CNNs) and vibration analysis; however, ...

In this study, a novel design for tilted spoke-type hybrid permanent magnet synchronous motor (TH-PMSM) that uses two types of (PM) materials is proposed to reduce the consumption rare-earth PM materials. The key feature securing space by tilting magnet, so more PMs can be used in limited rotor space. addition, based on centre axis rotor, magnets are positioned deeper inside than ferrite maximi...

This paper describes an interior permanent magnet synchronous motor (IPMSM) based on a new adjustable field method. The proposed PM achieved magnetic control utilizing saturation. In this paper, back electromotive force (e.m.f.) measurement test and load using the prototype were conducted to clarify if had wide operation range. e.m.f. test, it was confirmed that controllable range of 51.7%. add...
