“…If the stator winding grooves are large enough to allow a second winding to be wound in order to start softly in IMs, in this case, the soft start of the IM can be achieved with parallel winding, and the IM performance can be increased. As an example of this situation, a second winding was wound in the stator cavities in order to a soft start in one study [15]. In some studies, it has been tried to determine the most suitable coil pitch in order to minimize the noise arising due to spatial harmonics in the air gap where the rotating magnetic field between the stator and the rotor is located [16 -18].…”

Stator winding structures are one of the most important parameters affecting motor performance in induction motor (IM). When deciding on the coil pitch, the winding structure and the power performance of the motor are also taken into consideration. The stator coil pitch of the IM is known at the design stage of the motor. The stator coil pitch of an IM manufactured and in use may be wanted to be changed with the desire to improve the performance of the motor and suppress some harmonics. In this case, it is necessary to determine the motor winding structure and coil pitch by opening the stator cover of the motor, removing the rotor, and manually examining the stator winding structure visually. However, this process prolongs this improvement process considerably. A system that can detect the stator coil pitch according to the stator current behavior while the motor is running can significantly shorten this improvement process. For this purpose, in this study, a deep convolutional neural network (DCNN) model that can automatically estimate IM stator coil pitch angle with an accuracy rate of 100% is designed and applied.

“…For a 2-pole motor connected to a 50 Hz supply, the synchronous speed 3000 rpm, for a 4-pole machine, the synchronous speed is 1500 rpm. The ends of every coil are connected to form a winding which is connected to the terminal box in either in star (Y) or in delta (∆) to form the 3-phase load [19,20,21]. The start point is not earthed.…”

“…Also, these motors are available for three-phase or single-phase supplies and also available in multiphase Nowadays open winding induction machines are more popular for drive applications [2,[9][10][11]. Even though the induction machine is less costly, most of its practical use is for limited types of load at constant speeds although multiphase concepts and advanced control schemes have recently also been proposed [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. In [27], an integrated converter for a 48 V micro/mid hybrid electric vehicle (HVE) was proposed.…”

Abstract:In this article a new distinct winding scheme is articulated to utilize three phase induction machines for multifunctional operation. Because of their rugged construction and reduced maintenance induction machines are very popular and well-accepted for agricultural as well as industrial purposes. The proposed winding scheme is used in a three phase induction machine to utilize the machine for multifunctional operation. It can be used as a three-phase induction motor, welding transformer and phase converter. The proposed machine design also works as a single phase induction motor at the same time it works as a three-phase to single phase converter. This new design does not need any kind of special arrangement and can be constructed with small modifications to any standard three-phase induction motor. This modified induction machine is thoroughly tested to determine its efficiency and other parameters and also hardware implementation results are provided in the article, which validate the design and construction.
