This study investigates the influence of buried magnet arrangement on efficiency and drivability performance provided by an on-board interior permanent synchronous machine for a four-wheel-drive electric car with two single-speed powertrains. The relevant motor characteristics, including flux-linkage, inductance, electromagnetic torque, iron loss, total efficiency, are analyzed set six configur...

An interior permanent magnet synchronous motor (IPMSM) drive system with machine learning-based maximum torque per ampere (MTPA) as well flux-weakening (FW) control was developed and is presented in this study. Since the performance of IPMSM varies significantly due to temperature variation magnetic saturation, a MTPA using Petri probabilistic fuzzy neural network an asymmetric membership funct...

This paper focuses on three commonly used sensorless methods based on high-frequency signal injection; namely, the rotating sinusoidal injection in the stationary reference frame, the pulsating sinusoidal injection in the estimated synchronous reference frame, and the pulsating square wave injection in the estimated synchronous reference frame. Although these methods have found applications in ...

A dual mechanical port machine (DMPM) is used as an electrically variable transmission (EVT) in hybrid electric vehicle (HEV). In the conventional HEV, this machine is replaced by a planetary gearbox and two electric machines and makes this structure simpler. This paper presents field oriented control (FOC) for DMPM. For HEV application, drive efficiency and wide operating speed range are impor...

Axial field flux switching motor with sandwiched permanent magnet (AFFSSPM) is a novel of flux switching motor. Based on the vector control method, the mathematical model of the AFFSSPM is derived and the operating performance of the AFFSSPM in the overall operating region is investigated.A novel control method for the AFFSSPM drive system, including the id =0, maximum torque per ampere, consta...

This paper proposes a loss minimization control method based on improved gradient descent algorithm (GDA) for interior permanent magnet synchronous machine (IPMSM). Since the power of PMSM is derived from measured phase voltage and current, this independent iron model containing motor parameters. Meanwhile, it can guarantee stability system when entering searching period. Both maximum torque pe...

Recently, Inner Permanent Magnet (IPM) Synchronous Motors are known as a good candidate for hybrid electric vehicle traction drive application due to their unique merits like little volume, light weight, high efficiency and power factor and high reliability. However, behavior of this motors is quite depending on airgap length. This paper discusses the effect of airgap variation on d-q equivalen...
