A Non-isolated Modified Zeta Converter-fed DC Motor under Load Condition [PDF]

open access: yesBrazilian Archives of Biology and Technology
In this paper, the steady state performance characteristics of a separately excited DC motor fed by a non-isolated positive output DC-DC converter of high voltage gain Zeta topology are presented. The suggested Zeta converter configuration energized by a

Chaoization of DC Motors for Industrial Mixing

open access: yesIEEE Transactions on Industrial Electronics, 2007
Conventional industrial mixing is ineffective, which consumes a lot of energy. In this paper, an effective mixing approach is proposed and implemented by using an electrical chaoization. Namely, a permanent-magnet DC motor, which acts as the agitator, is electrically chaoized by time-delay feedback control.

Mechanical Fault Detection on Electrical Machine: Thermal Analysis of Small Brushed DC Motor with Faulty Bearing

open access: yesMATEC Web of Conferences, 2018
Direct current motors (DC motor) are used in the small electric devices commonly. DC motor are cheap and easy to install, thus their popularity. Despite the popularity, faults occur which make diagnosis and detection of faults very important.

Impact of PWM strategies on RMS current of the DC-link Voltage Capacitor of a dual-three phase drive [PDF]

open access: yes, 2014
The major drawback of usual dual three-phase AC machines, when supplied by a Voltage Source Inverter (VSI), is the occurrence of extra harmonic currents which circulate in the stator windings causing additional losses and constraints on the power ...

Comparison of Two DC Motor Speed Observers on Sensorless Speed Control Systems

open access: yesJurnal Nasional Teknik Elektro dan Teknologi Informasi, 2022
In a sensorless motor speed control system, the motor speed is not directly measured using a speed sensor, but it is estimated using an observer. The sensorless speed control systems are mostly applied to AC motors, while they have not been widely ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Control of separately excited DC motor with series multi-cells chopper using PI - Petri nets controller

open access: yesNonlinear Engineering, 2019
The separately excited Direct Current (DC) motor is widely used in many industrial sectors. During the operation of the DC motor, the load torque and the voltage of the network can cause a destabilization of the actual speed and actual current. Thus, the
