permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. one of the interesting applications of such motors is in underwater vehicles. in these cases, reaching to minimum volume and high torque of the motor are the major concern. design optimization can enhance their merits considerably, thus reduce volum...
In this paper, A power factor correction (PFC) based single ended primary inductor converter (SEPIC) is used to regulate DC bus voltage of voltage source inverter (VSI) to run PMBLDC motor . Permanent magnet brushless DC motor (PMBLDCM) is used in air-conditioning systems and runs at rated torque and variable speed to achieve energy conservation. The analysis, design and performance of the prop...
Permanent magnet synchronous motor (PMSM), employing vector control, is used in high performance servo drive applications. It is highly non-linear plant which can be described by linear parameter varying (LPV) state-space model. In order to solve nonlinearity problem and syntesize speed controler, tensor product (TP) model transformation is proposed. Using this transformation, given linear para...
This paper describes the design of a direct-drive permanent-magnet generator for use in a novel sea-wave electrical generator. The basic system is briefly described and the target specification derived from the device and the wave tank performance. The design for the brushless permanent-magnet generators is then developed using SPEED PC-BDC and verified using finite element analysis (PC-FEA). A...

Among the different Magnet Brushless DC motors (PMBLDC) as well permanent particularly EV owing to high-speed performance constant speed-torque features. In this paper, PMBLDC motor is modelled analysed mathematically using its equival...
Application Characteristics of Permanent Magnet Synchronous and Brushless dc Motors for Servo Drives
The permanent magnet synchronous motor (PMSM) and the brushless dc motor (BDCM) have many similarities; they both have permanent magnets on the rotor and require alternating stator currents to produce constant torque. The difference in these two machines is that the PMSM and the BDCM has sinusoidal and trapezoidal back emfs, respectively. This means these two machines have different operating c...
In this paper effort is made for the torque ripple minimization of 70 W, 24 Volt, 350 rpm, surface mounted radial permanent brushless DC (SPM BLDC) motor. The stator slot shaping is analyzed. The results obtained from FE analyses have been discussed. Design of stator slots have influence upon the cogging torque. Options available for slot designs viz, square type slots, square with curved tangs...
