Phase Synchronous Motor Starter Circuit

Operation of three phase synchronous motor starter circuit
During starting, a three phase synchronous motor opeerates as a normal onduction motor. After three phase power is connected to the system, all the three main comtacts “M” close and the auxilliary contacts change state, the normally opena contacts close while the normally closed contacts open. The three phase current then flows through the overload heaters into the the three motor stator leads. The current therefore flows through the stator windings causing a rotating magentic field. This rotating field interacts with the induction windings in the rotor causing it to rotate Continue reading...

1. Product introduction
In November 2014 Toyota Motor Corporation released its new 2015 Toyota Corolla (Latest Car Reviews). The 2015 model of Toyota Corolla did not drastically change comparing to its previous model in 2014. Yet the manufacturer improved several features of this car in order to better meet market expectations.
It is important to mention that there are several powerful competitors in the market segment, in which Toyota Corolla is sold, such as Honda Civic, Continue reading...

Three phase motors are powered by three phase mains power supply. The stator in a three phase motor has provisions for slots that can accommodate three phase winding. The three phase windings are arranged so that they can produce a rotating magnetic field. The rotor has parallel laminated conductors shorted at the ends by the end rings. The conductors are made of heavy copper or aluminum bars and are skewed from the central axis. This prevents poles from locking which can cause magnetic humming or stalling of the motor. Three phase motor starting circuits control motor starting speed by Continue reading...

1. Mechanism that result in a patient showing hyperreflexia and hypertonia
Hypertonia is muscle stiffness. It can also be associated with the increased muscle tone. Reflexes (such as a knee-jerk reflex) in hypertonia are stronger or increased. Hypertonia may hinder walking, movement or speech of a man. Muscles are strained and tight to the touch. Tonus is increased by the spastic type; muscle tone in the study of the resistance is felt at the beginning of the movement (a symptom of ‘folding knife’). The obvious hypertonia is characterized by contracture. In hemiplegia (hemiparesis) in hand, tone increases in adductor Continue reading...

Individuals with physical disabilities display a very wide and incredibly varied range of impairments that affect their function in a myriad of ways. While many specific motor impairments are associated with certain disabilities, most with physical disabilities are unique in the extent, severity, and nature of their motor impairments. One child or adult with cerebral palsy may present with completely different motor impairments than another child with the same diagnosis.
When working with individuals with disabilities, in order to understand the person’s physical functioning it is important to understand the characteristics of motor impairments. It can be difficult Continue reading...

Variable Frequency Drives

Introduction
VFD is a system of control rotor speed asynchronous (or synchronous) motor. It consists of the motor and the inverter. Frequency converter (inverter) is a device consisting of a rectifier (DC bridge), which converts AC power to DC power, and an inverter (converter, sometimes with PWM), which converts direct current into alternating required frequency and amplitude. Output thyristors (GTO) or IGBT transistors provide the necessary current to power the motor. To avoid the inverter overloading with great length between the inverter and the feeder chokes are put. To reduce to reduce EMI it is being used EMC-filter.

The Use of Electricity and Magnetism in Our future Transportation.

The discovery of electricity ranks among the most important discoveries in the history of modern humankind. Man has gone on to have such a huge dependence on electricity in all aspects of life, that it is sometimes difficult to imagine a world with no electricity. As the world continues to become even more industrialized and developed, this reliance can only continue to grow, and the benefit and value of electricity in our lives will gain more significance. Various theories of electricity have emerged over the years, with plenty of innovations resulting. Knowledge of magnetism has also been in the Continue reading...

If there is an aspect that a prospective company should never overlook is the aspect of seeking to expand the market to the international platform. Globalization has wiped out the national and cultural boundaries, and thus reducing the world into a single marketplace. Mrak (2010) asserts that with globalization, businesses have been exposed to a plethora of marketing opportunities across the world. Furthermore, the uninterrupted advancement in technology being experienced throughout the world has facilitated the capabilities the opportunities of international markets. For instance, air travel and the advent of the internet have eased global communication and thus the Continue reading...
