motor controllers.
So can anyone tell me how a controller for a PMDC motor is used.
How is it connected to the motor and what are the parameters that it can control.
What are the general specifications these controllers have ?

Harshad ItaliyaAre you talking about BLDC motor control?

Abhijeet Khandagalei use L298/3. one end is for logic input from controller. other is for motor analog output. speed, direction and enable can be controlled. google those ICs. need any help, get in touch.
-
Abhijeet Khandagalealso specify what motor you are using. can be answered better.

Well i am going to use 12 volt 56 amp permanent magnet dc motor. can you explain the concept of these motor controllers in detail.

whats BLDC -
Abhijeet Khandagaleplease specify the use. that one is a heavy duty i guess. you will require a different motor driver. they work on a circuit called the H bridge. will share a article. BLDC is brushless DC motor.

well i am not gonna use BLDC.
we are building an electric car, and this motor is going to power it. now i am looking for a controller which will control its speed as well as direction of rotation. i also want to know how this controller can be interfaced to the accelerator pedal. -
Abhijeet Khandagalenow we're talking! will have to do a bit of research on it. haven't worked on high amp motors. give me some time.

zaveriok dude take your time.

Abhijeet Khandagalegoogle H Bridge.

Speed of permanent magnet dc motor can be controlled by varying the voltage applied to the armature. Feedback devices sense motor speed and send this information to the control to vary its output voltage up or down to keep speed at or near the set value.zaverinow i am looking for a controller which will control its speed as well as direction of rotation.
Feedback techniques include voltage tachometers, optical encoders, electromagnetic pulse generators,
and back emf monitoring. And by using thyristor firing pulse controller, voltage can be controlled.
P.S: correct me if I am wrong -
Abhijeet Khandagale#-Link-Snipped-# that's theory. what he needs is a practical solution. controllers are available in the market. need to hunt them that's all.

you are right , but right now the motor is gonna be controlled manually, and will not incorporate any of that mechatronics stuff. -
zaveriok one last thing, for a 12volt motor, what should be the voltage range for the controller ?

Ramani AswathThis may give you some pointers:
