Hello All,
Great to see your replies.
Let me give you more information on this.
I have dynamo meter set up where I have checked combined efficiency by using o/p / i/p.
But they are asking me only controllers/ drivers efficiency.
Could you please help me?
Hello All,
I have developed BLDC motor controller. I have been asking below questions in my product demonstration,
1) What is the efficiency of the Controller?
2) What is the efficiency of Motor?
I have checked combined efficiency (i.e. controller + motor ) which is 89%.
Kindly help me how...
Hello Everyone,
I am facing an issue with ADS1115 ADC which is 16 bit ADC. I am able to communicate mircocontroller and ADC. I am even able to get the ADC counts. Though counts are fluctuating I have used averaging method to get proper counts.
The PGA is +/- 2.048. I am using channel 0. I am...
Hi everyone,
Hope you guys are doing well.
I am trying to meaure the current through the motor using sense resistor of 10mohm.
I am using LM324 as a differential Op-amp.
The circuit description is as follows,
1) The sense resistor is connected in between 12V positive supply and motor . It...
The problem is while selecting a part number. The next step after selecting a part number is to choose program file. But the problem is with part number selection then I am not able to go ahead and select the program.
Hello,
Merry christmas to everyone.
I am using Emp-30 to program a PLD part number ATF16V8BQ which is from Atmel.
I am facing below error while selecting a devices.
Device algorithm Atmel ATF16V8BQ failed to initialise.
Can you please help me to understand how to resolve this.
I have done the same.
I am not geeting any adc having following specs,
ADC-16bit and 24bit
Only positive scale required.
do not need negative values.
single ended o/p ,I2C compatible ADC
may you guys may know better option for the same. please suggest.
Hello everyone,
Can you please suggest me single ended o/p ,I2C compatible ADC
24bit,16bit
I dont need negative values.
It will be more helpful for me.
Hello All,
I am interfacing ADS1501 12 bit ADC with controller. I am getting proper o/p form 0 to 0x7fffh with variable POT of 1k,5ketc.
Now thing is that 12 bit ADC should get result o/p upto 0x1000h but I am not getting that much of value.
My supply voltage is 5V and I have used 10kohm...
Hello C_mintra,
thanks for the doubts.
All for loops are generating delay. This delay is just for protection. Some Power supplies probably won't give 12V directly when power ON. They are like 2V.....3V......7V......10V....12V after power ON. That is why delay is added.
EI(); is the enable...
Anything wrong with the code?

The issue is still pending. Everytime motor needs initial start up by hand then motor is properly working. I am also getting good torque. But the issue is in first start.
Awaiting for your reply.
All guys please reply me.
Hi,
This function is used change the duty cycle.The number 2 defines which bottom mosfet to trigger and ducycle assigns duty cycle.
Awaiting for your reply.
Hello Easyrider,KluasST,C_mintra, all others,
Please find the attached code for review.
