It results in … WebMar 19, 2024 · The correct answer is option 4): (Decreasing magnetic current and increasing power factor)Concept: Slots in Induction motor: The speed of the induction motor is inversely proportional to the load torque.In semi-closed and closed slots, the air gap between the stator and rotor is small as compared to open slots.
Question is ⇒ Semiclosed or totally closed slots are used in …
Webthis work, the possibility to use magnetic wedges in induction motors with semi-closed slots is studied. This strategy allows to reduce copper and core losses, therefore increasing then the motor effi-ciency. The study analyses low power motors and considers different permeabilities and geometries for magnetic wedges. http://repository.unp.ac.id/23242/1/%282b%29%20p560-purwanto.pdf swatch618

WebMar 1, 2024 · This paper investigates the application of using magnetic wedges in a semi-closed slot bearingless induction (BI) motor. In this strategy, the electrical loss of the motor can be reduced, improving the overall efficiency. At the same time, the temperature rise of the winding is reduced, and the vibration and noise levels are greatly depressed ... WebThe inductance of a closed-slot bridge, that is, its leakage reactance has been problematic due to saturation of a magnetic steel sheet at a bridge. In this paper, the … WebA spindle motor with 14 kW output, 4 Poles, and ∆ connection, operating at 380 V and 30000 rpm was used in this study. The spindle motor was constructed using a rounded semi-closed stator slot, as shown in Fig. 1. The general specifications of the spindle motor are listed in Table 1 and analysis procedure is depicted in Fig. 2. Fig. 1. skullcandy uproar wireless sale
