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 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 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 are the types of motor controls?
motor can be control by using variable frequency drive
The speed of an electric motor can be controlled by?
By using the star- delta starting methodBy using variable rhoestatsBy using auto transformers
How do you control the speed of the induction motor by using cycle stealing method?
The speed of an induction motor depend on the frequency of the supply voltage 60Hz in the USA and 50Hz in most other country's and the speed can only be controlled by varying the frequency, the way to do it is to rectify the AC to DC and convert it back to AC but with another frequency. I'm planing to post a project on my website soon, so look out for it at http://www.patenttrade.net
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.
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.
Speed control of a.c motor?
Use a variable Frequency Drive. Sold by ABB, Allen-Bradley, and many others.
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.
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
How control dc motor using micro controller?
The speed of the motor depends on load, voltage and current. The speed can be maintain by using a method called Pulse code modulation (PWM). By changing (modulating) the width of the pulse applied to the DC motor we can increase or decrease the amount of power provided to the motor, there by increasing or decreasing the motor speed. mean we have to just change the duty cycle of modulating output.
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.
