“…From (12), it can be found that the electromagnetic damping force has relations with the pole pitch and the length of the extra yoke. Increasing the pole pitch or the length of the extra yoke will also increase the length of aluminium tube, hence the damping effect is more obvious.…”

“…Therefore, it is important to reduce this damping effect. Fortunately, the relative literature that focuses on eddy-current effect in permanent magnet synchronous motor (PMSM) and rotary voice coil actuator (RVCA) open up a new horizon for us [12][13][14]. In [12,13], laminated cores and sleeve openings have been used to reduce the eddy current on the retaining sleeve in PMSM.…”

In the case of designing linear voice coil motors (LVCMs), the aluminium tube is usually used to support and fix the windings. Due to the high-speed linear reciprocating motion, the eddy-current damping force in aluminium tube has a large effect on the dynamic characteristic of LVCMs and weakens the resultant force. In this study, an LVCM with forward winding is studied. The cause of eddy current damping force in the original structure of the aluminium tube is analysed, and the corresponding mathematic model is established which is verified by finite element method. To restrain the damping effect, three restraining measurements have been discussed. Then a novel structure of aluminium tube with axial slits and ribbed stiffeners is proposed according to the simulation analysis. During the experimentation process, the mover resultant force is replaced with its acceleration. Results show that the mover acceleration of LVCM with stiffened aluminium tube is bigger than that of the initial one. Hence the resultant force of the proposed structure is improved effectively and the new structure has a good inhibition effect on eddy-current damping effect.

“…Studies on BLDC's generally focus on magnet geometries and motor control [11,12]. Recent studies on the interaction between the number of poles and the number of slots in electrical machines have also been conducted [13][14][15]. Studies on optimization of total harmonic distortion can be classified into two groups.…”

Brushless DC motors (BLDC) are widely used in variable speed drive applications. Nowadays the relationship between the number of poles, slots and winding arrangements in BLDC motors continues to be a very challenging topic. The main objective of this work was to develop and compare four-pole BLDC motors with different slot numbers (6, 12 and 15) and winding arrangements. Three-dimensional finite element analysis (FEA) was conducted to characterize the proposed designs. The Total Harmonic Distortion (THDv) which tells the amount of harmonics present in the voltage have been obtained and compared based on the different slot numbers and winding arrangement. In the study, an extensive investigation of the THDv values in four-pole BLDC motors having different slot and winding configurations has been carried out. From the simulated results it is evident that the lowest THDv and corresponding sinusoidal back emf can be obtained by implementing 15 slots within four-pole designs. The performance values have been examined comparatively by analysing the motors at the rated condition.
