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 else can I help you with?
Can we interfacing stepper motor using 8086?
Yes, you can interface a stepper motor using the 8086 microprocessor. This typically involves using output ports to send control signals to a motor driver circuit, which then drives the stepper motor. You would need to write a program to generate the appropriate sequences of pulses to control the motor's direction and speed. Additionally, external components like transistors or H-bridges may be required to handle the motor's current.
Can a rheostat be used to control speed on a capacitor run motor?
No. If you attempt to reduce the voltage to a cap start motor by using a rheostat, you can destroy the motor.
How thyristor control the motor speed?
Thyristors control motor speed by regulating the voltage applied to the motor, which in turn affects its speed. By using phase control techniques, thyristors can adjust the point in the AC cycle at which they are triggered, effectively reducing the average voltage supplied to the motor. This results in a decrease in power and speed. Additionally, thyristors can be employed in various configurations, such as inverters or chopper circuits, further enabling precise speed control in different types of motors.
How motor can control using timer contactor?
Control means, a timer cant control is speed directly, it can control its operation. A times will have NO nd NC contacts. Connect the motor in series with the timer contacts wrt desired operation
What is the historical background for dc motor speed control?
The historical background of DC motor speed control dates back to the late 19th century with the advent of electric motors. Early methods of controlling speed included varying the voltage supplied to the motor, using resistors or rheostats. The development of more sophisticated electronic control techniques, such as pulse-width modulation (PWM) and feedback control systems, emerged in the mid-20th century, enabling more precise and efficient speed regulation. Today, advanced digital controllers and microcontrollers have further revolutionized the field, allowing for highly responsive and adaptable speed control in various applications.
Speed control of motor using SCR?
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
Can we interfacing stepper motor using 8086?
Yes, you can interface a stepper motor using the 8086 microprocessor. This typically involves using output ports to send control signals to a motor driver circuit, which then drives the stepper motor. You would need to write a program to generate the appropriate sequences of pulses to control the motor's direction and speed.

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
How do you control speed of AC servo motor?
well, you either have to program the operating frequency crystal to a better remote control, (if you are using a remote control,get remote control which can control the speed) or, try using a more powerful or less powerful battery to increase or decrease the speed.
Can a rheostat be used to control speed on a capacitor run motor?
No. If you attempt to reduce the voltage to a cap start motor by using a rheostat, you can destroy the motor.
How thyristor control the motor speed?

Speed control of a.c motor?
Use a variable Frequency Drive. Sold by ABB, Allen-Bradley, and many others.
How do you change a degree of rotation in stepper motor using 8085 microprocessor?
To change the degree of rotation in a stepper motor using an 8085 microprocessor, you first need to determine the number of steps required for the desired rotation. This is done by calculating the steps per degree based on the stepper motor's specifications. Then, you can write a program in assembly language to control the motor's step sequence using output ports connected to the motor driver. By sending the appropriate sequence of signals for the calculated number of steps, you can achieve the desired rotation.
What is ac drive and how it works?
An AC Drive used for a speed control of a motor by using vary frequency.
What are the advantages of speed control of DC motor using micro-controller when compared to other?
This motor is able to work from the battery. The speed is less complicated to use and you do not need much voltage.
How do you reduce the speed of a 15 kW 3 phase motor without using variable speed control?
If the load is connected to the motor via belts, you can change the speed the load is turning by changing the pulley sizes. To get the load to slow down, increase the size of the pulley on the load; to get it to speed up, increase the size of the pulley on the motor. To reduce the speed of the motor itself, you'll have to alter the line frequency, which you can't do without a variable frequency drive attached to the motor.
