Slotless tubular PM generator with dual quasi‐Halbach magnetized PM Array: Analytical and numerical magnetic field analysis

“…By using Struve Function, 17 an answer to Poisson's equation is assumed as (13); hence, in the current region, the magnetic flux density calculated as (14) and (15):…”

“…A finite element method (FEM) analysis of static thrust and magnetic flux density distribution for a 10 kW, LSG, which has an efficiency of 97% for an FPEG application is presented in the study of Yamanaka et al Initial design and electromagnetic field analysis based on ANSYS Maxwell for a Tubular Linear Generator (TLG) with radial and axial PM in free piston engines is discussed in the study of Subramanian et al In this study, flux density, Back‐EMF of the proposed machine have investigated, and the obtained results showed that the machine with axial PM provides extra output power and efficiency in comparison with the machine with radial PM. A FEM‐based static thrust and magnetic flux density distribution of a novel FPEG configuration, which is applicable for hybrid vehicles, is presented in the study of Yamanaka et al In the previous studies, an improved flux path Homopolar BLDC generator has been investigated in which PM is replaced by a direct current excited auxiliary field winding to control the main magnetic flux pass through the machine. This property improves controllability of the magnetic flux and terminal voltage for wide range of operation.…”

Control of BLDC motor using MRPID controller with modified landsman converter

“…A PF bridgeless modified Landsman converter is introduced for BLDC motor drive to reduce the current stress and improved efficiency of the overall system (Ramya et al , 2018). Via utilizing the artificial neural network, in low and high speeds for an ampere to expands the torque at a versatile control schema, the angles of triggering are self-tuned (Cheshmehbeigi and Karami, 2018). The torque is classified into two elements; the primary element of the torque, the interactivity betwixt the stator currents and magnets, is termed to traditional torque; another torque element is because of the interactivity along the eddy currents in the protecting cylinder (Hannon and Dupre, 2018).…”

Design and analysis of a pulse capacitor charge power supply system based on novel brushless field assisted induction generator with flux control capability

“…As the main salient feature of including the DC field coil, which increases controllability of the flux, providing a regulated terminal voltage in a very wide range appropriate for variable speed applications can be addressed. In [11], an improved flux path homopolar BLDC machine has been presented, in which PM is replaced by a DC excited assisted field coil to control and regulate the flux. In [11], for different values of speed, maximum torque has been determined by calculating the optimal turn-on and turn-off angles and the optimal field current which provides more flexible control over wide ranges of speed.…”
