1.3 Explain the difference between the drive braking modes? 0. Ramp Power input to the motor is reduced gradually, following a determined ramp path. 1. Coasting Power is turned off instantly and the rotor is allowed to freely spin until it stops. 2. DC Brake A DC source from the generates a permanent magnetic field in the stator which creates an EMF in the windings of the rotated rotor, causing the braking current. Interaction of the permanent stator flux and the rotor current produces the braking torque. 1.4 When the sensorless vector control is required? Sensorless vector control is beneficial when there is a need to save money on building the drive. With sensorless vector control, costly hardware such as tachometers can be left out from the construction of the drive. 1.5 Call the drive faults you met. How do you avoid and clear these faults?

Wilhelm Eduard Weber (24 October 1804 23 June 1891) was a German physicist. * Saksa füüsik, kes koostas absoluutse mõõtühikute süsteemi. Ta ehitas Saksamaale esimese elektromagnetilise telegraafi * Tema nime kannab magnetvoo mõõtühik. The SI unit of magnetic flux, the weber (symbol: Wb) is named after him. Heinrich Rudolf Hertz (February 22, 1857 January 1, 1894) was a German physicist who clarified and expanded the electromagnetic theory of light that had been put forth by Maxwell. He was the first to satisfactorily demonstrate the existence of electromagnetic waves by building an apparatus to produce and detect VHF or UHF radio waves.

Baroque was to prove to be the ideal style to reflect what was deeply broken society, one that was to remain in political and religious turbulence until the II half of 18th C. It always portrayed precisely that scenario: forces in conflict, opposites and extremes confronting, and at the same time, seen to be manifestations of an ordered whole. Role: to give the thruths of the sphere of heaven (fixed, immovable and permanent). Art of Baroque: flux and paradox, illusion and seeming, searching for eternal thruths. Vehicle for new and very emotional piety of Counter-Reformation Catholicism, ideal to express absolute monarchy. It was expensive style, although its role was to give an aura of divinity and autocracy on Charles II, couldn’t hide that he was kept in power by the will of Parliament. 13.

English literature is one of the oldest literatures in Europe; dates back to the 6th century AD. Oral literature, i.e. not written down, spread from person to person. In 449 AD Anglo-‐Saxon tribes invaded England – beginning of the Anglo-‐Saxon period in English literature. The first form of literature was folklore, carried by scops and gleemen, who sang in alliterative verse (a kind of simple poetry). Prose developed much later. The first form of recorded English literature was the epic Beowulf, which was produced sometime near the end of the 7th and beginning of the 8th century. It has no ...
But in 1572 something happened. A new star appeared in the constellation of Cassiopeia. The new star was observed by the Danish astronomer, Tycho Brahe(15461601). The star was brighter than any other star for more than two years contemporary accounts tell us that the star was so bright that it could be seen in daylight. And in 1600, another star appeared. This star was observed by Johannes Kepler(15711630). The heavens seemed to be in flux [ jõuväljas ]. Such occurrences made lasting impressions on all men, whether scientist or not. After all, this was an age in which men believed their fate to be written in the stars and now those stars were changing

Magnetic Sensors Hall Effect Sensors Probably the simplest magnetic sensor to use in an embedded application is a Hall effect sensor. The Hall effect was discovered by Dr. Edwin Hall in 1879. He discovered that if a magnetic field was placed perpendicular to one face of a thin gold sheet in which a current was flowing, a voltage would appear across the sheet (Figure 3.24). This voltage is proportional to the current flowing in the sheet and the magnetic flux density. A Hall effect sensor is made from silicon, and the Hall voltage produced in silicon is only a few microvolts per volt per gauss. Consequently, a high-gain amplifier is required to bring the signal from the Hall element to a useable range. Hall effect sensors integrate the amplifier into the same package as the sensor element. Hall effect sensors are available as sensors that produce an output pro- portional to the magnetic field, or as switches that change state when the mag-
