“…This type of modelling, therefore, allows space harmonics to be taken into account even if the CMCM does not consider certain phenomena (saturation, skin effect, etc.). Thus, despite its weaknesses, the CMCM approach offers better precision, calculation time, and adaptation to modelling most faults of electromagnetic origin in electrical machines [15].…”

The development in industrial systems leads to the augmentation in the consumption of the power. Therefore, this development makes use of multiphase machines. The use of multiphase machines caused several problems and defects. Electrical energy is mainly distributed in a three-phase system to provide the electrical power necessary for the electrical engineering equipment and materials. The sinusoidal aspect of the required original voltage primarily preserves its essential qualities for transmitting useful power to terminal equipment. When the voltage waveform is no longer sinusoidal, perturbations are encountered, which generate malfunctions and overheating of the receivers and the equipment connected to the same electrical supply network. The main disturbing phenomena are harmonics, voltage fluctuations, voltage unbalances, electromagnetic fields, and electrostatic discharges. This present work aims to study the effects of harmonic pollution and voltage unbalance on the five-phase permanent magnet synchronous machine using spectrum current analysis and wavelet transform.

“…The structure of brushless DC motor mainly consists of a stator with three-phase winding and a rotor with permanent magnetic poles [4][5]. The stator is mainly composed of core and winding, the stator core is generally made of silicon steel laminated into a ring-shaped punch with a slot, the slot is embedded with the stator winding, the stator winding is generally divided into three phases and often uses the whole distance concentration winding; rotor is the rotating part of the excitation field, composed of permanent magnet steel according to a certain number of pole pairs, the shape of the rotor magnet is arc-shaped, the air gap of the stator and rotor under the magnetic pole is uniform, and the air gap flux density is trapezoidal distribution [6][7][8].…”

Permanent magnet brushless DC motors have the advantages of small size, easy control, and large speed range, and are widely used in mechanical equipment and electronic equipment. However, due to the influence of speed pulsation, the permanent magnet brushless DC motor is limited in the drive system. Therefore, this paper adopts the three closed-loop control strategies of speed loop, current loop and position loop to model the permanent magnet brushless DC motor and control the speed. , can effectively suppress the torque ripple, and improve the performance of the permanent magnet brushless DC motor to a certain extent. It can be seen from the simulation results that under the position step signal, the permanent magnet brushless DC motor designed in this paper can achieve a good tracking effect.
