Permanent magnet machines are very suitable for Electric vehicles and Motor pump applications because of their simple construction, ease control high efficiency. 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...

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...

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...
