How to control speed of dc motor using microprocessor 8085?
Here the DC motor is controlled by the microprocessor (8085). The kit used was dynalog 8085 kit. The DC motor is very difficult to control unlike the stepper motor, which can be controlled by giving the appropriate CONTROL WORD. By knowing the DC motor theory we know the different methods used to control the motor, the most primitive and the once upon a time the most popularly method was WARDLEONARD motor speed control, but this had many disadvantage, so the world of Electronics brought in the thyristor control, which were very flexible and can be employed to use AC instead of DC cause they had a inbuilt convertor. The thyristor-based system is good but when used with Microprocessor based speed controller they are really good. We have shown the block diagram, circuit diagram used by us to control a small tape recorder sized motor
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.
How does the starting of synchronous motor using dc generator as a load work-?
Starting of the synchronous motor using the DC generator creates a magnetic field.
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.
Why is DC series motor is used more than shunt wound DC motor?
Series DC motor develops a very large amount of turning force called torque from standstill and can be operated by using either an AC or DC power source.
How you control speed of dc motor by gsm?
using a programmed microcontroller, modem and other components like RS232, ATcommandes etc you can do it.
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.
How do you introduce feedback circuit in dc motor speed control?
By using your brain
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.
How does bridge rectifier control a DC motor?
give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
What is a DC shunt motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
What is self control of synchronous motor drive?
the self control of a synchronous motor is done using an inverter fed through a dc link.speed is controlled by varying the output frequency of the inverter by controlling the dc link voltage
What is a shunted motor?
A DC shunt motor is a motor using DC supply with the the inductor connected parallel to the armature.
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.
Is DC motor used in a textile mill?
yes dc motor is used in textile mills for presicion control.
