This paper is devoted to the modeling and dSPACE implementation of three-phase squirrel-cage induction motor control using the constant Volts per Hertz principle and rotor flux oriented control (RFOC) strategy. A fuzzy PI controller is used in the speed control loop. Experimental results are compared for two different controls using a dSPACE system with DS1104 controller board based on digital ...

the paper presents the methodology for obtaining the level of noise in three-phase induction motors with squirrel cage rotor. Investigations include a single-speed motor with 3000 r/min and a two-speed motor with 750 and 1500 r/min. The investigated motors (manufactured by a Romanian company) were placed in a semi-anechoic chamber in order to determine the noise-to-frequency characteristics (sp...

The acoustic sound level caused as secondary effects of industrial energy conversion processes is often perceived as an unwelcome noise emitted into the enclosing surrounding. In order to verify design aspects for reducing such undesirable noise emission in particular within variable electric speed drive applications, suggested novel combinations of electrical and mechanical motor topologies ar...

This article presents a comparative analysis of the direct torque control with space vector modulation method for seven-phase squirrel-cage induction motor during encoder failure. The model reference adaptive system current and estimator system—flux based applied in loop speed have been analyzed. mathematical system-type estimators described. to voltage source inverter, controlled motor, has op...

The wind energy is free, inexhaustible and it produces no waste or greenhouse gases. Furthermore, it is a good method of supplying energy to remote areas. With growing application of wind energy conversion systems (WECSs), various technologies are developed for them. Squirrel cage induction motors are the most commonly used electrical machine in AC drives. In this paper, a new wind energy conve...

This paper presents the designing of the main dimensions and the selection of the magnetic and electric loading for different rating of squirrel cage induction motors to reduce the overall losses and to improve the power factor. A software development strategy for the design of main dimensions and the effects of various factors are studies to select the best parameters for the particular rating...
