Single-phase induction motors are widely used today. A single-phase motor is operated using a inverter. The inverter consists of four MOSFETs, two for the high side and low side. constant speed motor. As corollary, control Single-Phase Induction becomes very important necessity. Speed can be done in many ways. method followed this paper voltage control/ (V/F Control). By controlling duty cycle ...
The purpose of the present study was to investigate the effectiveness of Montessori method education on the visual-motor abilities of students with nonverbal learning disorders. For the purpose of this study, 4 first grade male students with nonverbal learning disabilities who were studying at Nabi Akram primary school in Bonab, during the academic year of 2019-2020, were selected based on the ...
Switched reluctance motor (SRM) drive has a remarkable characteristic, high efficiency, and good controllability, which makes it attractive for high-speed applications. In this paper, the basic control strategy for a switched reluctance motor drive circuit is explained and then three different resonant discharge topologies for SRM drive circuit are proposed. Due to resonantly discharging of exc...
Objective: Obesity is associated with numerous health problems such as dyslipidemia, hypertension, type II diabetes, cerebrovascular diseases, and coronary heart diseases. Gait as an effective factor in controlling obesity is very important in human motor development. Thus, the purpose of this study was to examine the effects of obesity and slimming on the gait kinematics in children. Methods:...
In this paper, the noise of electric motors is analyzed in order to obtain information for the detection of faults. Significant noise spectrum differences between healthy motor and motors with different faults are observed. The faults analyzed are bad bearing in the three phase induction motor and broken bars in single phase induction motor. The high-frequency spectral analysis of noise provide...
single-phase squirrel cage and three-phase induction electromotors are the most popular electromotors used in industry from long ago. when an induction motor starts with direct connection method, it takes a lot of current from the power supply (several times the nominal current); so, several methods have been devised to start such electromotors. these methods either reduce the voltage of the st...
This application note describes a driver solution for single winding single-phase BLDC, based on the PIC16F1613 microcontroller. The driver exploits two feedback loops: the inner loop, which is responsible for the commutation control, and the outer loop which is responsible for the speed control. The speed of the motor is referenced to an external analog voltage. Fault detection can be sensed d...
Single-phase induction machines are found in various appliances such as refrigerators, washing machines, driers, air conditioners, and fans. Large concentrations of single-phase induction motor loads such as air conditioners and other motorcompressor loads can adversely impact the dynamic performance of a power system. An understanding of the dynamics of this type of induction machine is needed...
