DC Shunt Motor Speed Control Methods
Просмотров 23 тыс.4 года назад
Speed control of DC Shunt Motor are classified into two types, 1. Armature voltage control method / Armature resistance control method 2. Field flux control method / Field resistance control method
DC Motor Characteristics-2/ Speed and Armature Current characteristics of DC Shunt and Series Motor
Просмотров 5 тыс.4 года назад
This concept reveals the response of torque and speed produced by the Motor during when the load changes are observed. There are three different characteristics of the Motor: 1. Ta vs Ia 2. N vs Ia 3. N vs T Having discussed first two in the previous online lectures, Let us see the third one in this session: Speed (N) vs Armature Torque (Ta) concerning DC Shunt and Series Motors.
Speed and Torque characteristics of DC Motor/ DC Motor Characteristics -3

 DC Motor characteristics unleashes the entire operation of the Motor.  Especially explores the behavior of the Motor under load.  In other words this concept reveals the response of torque and speed produced by the Motor during when the load changes are observed. There are three different characteristics of the Motor: 1. Ta vs Ia 2. N vs Ia 3. N vs T Having discussed first two in the previo...
DC Motor governing/operating equations
Просмотров 1,5 тыс.4 года назад
DC Motor governing equations provide great scope to understand the behavior and characteristics of the Motor. Not only that, typical relationships between input and output parameters are observed to make the analysis easy between them. There are only three main equations of focus, 1. Back EMF 2. Speed 3. Torque Obtaining output parameters in terms of the input parameters is a typical aspect of ...

To reveal the behavior of the DC Motor it is very important to investigate the characteristics of DC Motors, there are three different aspects of it: 1. Ta vs Ia 2. N vs Ia 3. N vs Ta Let us see the first one in this lecture
3 Phase Voltage Source Inverter - 180 Degrees mode
Просмотров 31 тыс.6 лет назад
Inverter is a power electronic converter that converts DC to AC. This discussion focuses on three-phase voltage inverter in 180-degree mode, working principle with the help of waveforms with a clear idea of the switching sequence of the solid-state switches present in the Inverter.
DC Motor Significance of Back EMF

Rotating Magnetic Field in the 3 phase Induction Motor is self rotating by its virtue. Kindly consider a change in current direction through three phase winding. Cross(❌) indicates the current inwards i.e., away from you (in to the board) and Dot(.) indicates the current outwards i.e., directed towards you. Regrets for having quoted reversely.

In the year 1831 Micheal Faraday has given laws of Electromagnetic Induction, based on which different methods of EMF are proposed.
DC Motor working principle
Просмотров 9 тыс.6 лет назад
DC Motor Principle: When ever a current carrying conductor is placed in the presence of magnetic field, a force is exerted on the conductor, hence the Motor rotates.
