“…Although the cross-coupling effect of the parameters have not been considered in the individual optimization, a ~5% higher average torque is achieved compared to initial design. ℎ 𝑠0 and ℎ 𝑟0 parameters were not optimized in this work since their impact on performance is insignificant or negative [55]. As a result, they have been set to their mechanically allowable limits.…”

“…In order to solve the starting problem of IMs, many researchers have explored the influence of the electromagnetic (EM) structure of the motor on the starting performance of IMs. [10][11][12][13][14]. Stermecki A. and Lee G. et al discussed the method of improving starting torque from EM structure of the motor by carrying out detailed studies on the optimal design of stator winding, rotor slot shape, and the shape of rotor bar [15][16][17][18][19].…”

In its applications, the starting performance of a 3-phase induction motor (IM) is very important. The starting torque of the motor should be as high as possible within the safe current range of the motor driver. In the study, the optimal frequency for motor starting is derived from the frequency characteristic of the IM. Through the analysis of the characteristics, the optimal frequency point can be found, which is able to generate the maximum torque per unit drive current. Both theoretical analysis and experiments show that the IM with the optimal starting frequency can generate the maximum torque for a given current. The traditional methods, such as soft-start, can reduce the starting current, but at the expense of lowering starting torque. This starting technology can solve the problem caused by traditional methods, improve the starting performance of the motor system significantly, and lower the requirement for the current redundancy of the motor driver effectively.

This paper presents the geometry influence of stator and rotor armatures on induction motor energy efficiency. The entire work is analyzed using a Motor-CAD programming environment. In principle, in the first stage, the influence of each armature is distinctly visualized upon loss level, for given effective power and given cooling algorithm through geometry changes that concern aspects related to the dimensions of the ferromagnetic core and the notches practiced within it. Afterwards, in a second stage, a synergistic modification of the induction motor geometry is carried out by cumulating the changes (cooperative effect) at the level of the two armatures, aiming to find the topology that provides – for some given effective power, and cooling algorithm – the highest energy efficiency.
