What is the difference between vector control and Stator Voltage control method of induction motor?
I need the answer of this question plz!!
In what two ways can the speed of a dc motor be varied?
speed of a dc motor can be varied by mainly two methods:- 1)field control method 2)armature control method further , field control method can be divided in 3 parts:- 1)field rhestat control method---speed variation is acomplished by means of a variable resistance inserted in series with shunt field 2)reluctance control method---by changing the reluctance of magnetic circuit by choosing right material.. 3) field voltage control method-requires variable field voltage supply. and armature control method can be divided in 3 parts :- 1)armature resistance control---variable resisitance connected in series with armature 2)shunted armature control. 3)armature voltage control. ------------mrityunjay pandey (kiit university ,btech 2nd year)
Can you suggest a circuit diagram for voltage regulation of 3 phase permanent magnet alternator for a constant output 230volts?
The normal method for controlling output of an alternator is to vary the field current. In a PM alternator, there would be no field windings to control. The only way I could think of would be to vary the speed of rotation. This might work if the output was rectified (DC), but would be a problem if the output is AC, since the frequency would also change. I have not seen a PM alternator per se. Unusual.
What is wye delta motor control?
It is a method of starting a three phase motor at a lower than operating voltage. The motor is operated at that voltage for a short specific time and then the controls switch to the motors full run operating voltage.
How are synchros used in error detection?
Control systems are synchros which are used in error detection. They provide a voltage to be converted to torque through an amplifying method.

How many Methods can be use to control the speed of Single Phase Induction Motor?
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method
What is the voltage output from alternator to battery?
Normal voltage will be in the 13.5 to 15 volt range engine running turning about 2,000 rpms. It shouldn't exceed 16 volts or it will boil your battery. If it does not run in this range then you need to replace the voltage regulator. These days that is usually done by replacing the whole alternator as a unit. It is usually the most cost effective method of repair.

What are the various method of speed control of 3 phase induction motor?
you can control the speed of a motor by changing frequency, increase or decrease the field winding or by voltage regulation. in these method you can controle the speed of athree phese motor SANDEEP SARKAR
What are the disadvantages of armature speed control method for a dc motor?
In armature speed control, speed can be varied only below the rated speed. Also in it voltage drops will be high.
What is Regulation of alternator by synchronous impedance method?
It is conducting OC and SC tests on the given three phase alternator and determining the regulation by synchronous impedance method.
What is the need of dstatcom?
DSTATCOM is one of the equipments for voltage sag mitigation in power systems. In this paper a new control method for balanced and unbalanced voltage sag mitigation using DSTATCOM is proposed. The control system has two loops in order to regulate compensator current and load voltage. Delayed signal cancellation has been used for sequence separation. The compensator should protect sensitive loads against different types of voltage sag. Performance of the proposed method is investigated under different types of voltage sags for linear and nonlinear loads. Simulation results show appropriate operation of the proposed control system.

Define methods of stress control in high voltage cables?
A method of stress control is controlling the distribution of dielectric stress. Uniform distribution of dielectric stress may be achieved in high voltage cables by surrounding the high stress areas of the high voltage cable with a tube of high permittivity material that makes contact at one end with a ground electrode contacting the shield of the high voltage cable.
