What is the importance of speed control of DC motor in industrial applications?
The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
Can a DC series motor with speed control be connected on AC supply?
A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
Future scope of dc motor speed control using rf?
The DC motor speed control has a scope of four speeds. The control speeds include; high, medium, low, and off.
Why do you control the speed of constant speed dc shunt motor?
no it controls your anus
Why speed control of DC shunt motor is necessary?
The total voltage of the batteries or DC power source connected to a shunt motor affects how first it moves. Increasing the DC voltage will make the shunt motor run faster.
What is DC drives?
A DC drive is a kind of equipment ordinarily do control a speed, tension and current on a Direct Current Motor (DC Motor), in order to have a certain process transformation under control.
Why do we connect a transistor to a DC motor?
Transistors are not normally connected to dc motors, but it is possible to use transistors in a speed-control mechanism for a motor.
How do you introduce feedback circuit in dc motor speed control?
By using your brain
Why do you control the speed of DC motors?
because dc motor is a powerful & dangerous motor it is akiller
Why ac drive convert ac voltage in dc?
It is done to control the speed of the motor.
What is Advantages of using a series DC motor?
The DC series motor is a high torque motor. so that it can pull heavy loads such as traction, lifts etc., the control of speed of a DC series motor is very smooth and easy.
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.
