    OK perfect. FvM, Schmitt Trigger and KlausSt I now fully understand what you meant. Many thanks. One Last Question: Hall Effect Sensors give information about Rotor Speed only. How to detect position of the Rotor (which indirectly means the Actuator)? One way is to keep track (memory) of...

    Do you mean that I should not attempt to drive the motor (and neither I should apply a voltage) when it is stationary? What it means? Pretty strange, isnt it? Of Course the motor will stop and start moving many times during the whole operation. Please elaborate your comment. Reagrds

    moved- FPGA based control of BLDC Motor (BLDC , FPGA , ADC , IGBT , MOSFET , 3 Phase)

    Respected All! A good day to everyone wherever you are OK. Please look at the new problem I am facing. The motor starting current is 90 Amp. The Drive IC can supply a maximum of 20 Amp. Please look at the attached image. Any comments over the issue? Further, can anyone explain me the...

    [Merged]Re: Selection of an ADC Chip Good Day Barry! Thank You for your reply. Well I am agreed that no ADC measures current. So Its always a voltage signal. Further, it is a CURRENT monitoring circuit. 3rd, both speed and resolution is not very strict requirements. The current is not...

    Respected KlausSt and Schmitt Trigger, I had a meeting with team member working on FPGA. He answered as follows: Interface? = SPI Sample Rate? = 10 Hz Reference? = External Supply Voltage, Dynamic Range? = We are not sure about the reply to this Qs. (Maybe 5V/3.3 will be used) Any Particular...

    [Merged]Selection of an ADC Chip Respected Technical Readers and Experts, Please have a look at the attached diagram. I am trying to find a suitable ADC IC which can be used to sense the current, convert it into a Digital signal for its reading by a FPGA. Please note that filtering means the...

    For respected KlausST Please suggest me a suitable ADC IC, which may be used for current sensing in this application. 10 Bit resolution would be sufficient.

    OK. That Sounds pretty nice. May you please share your views whether it is technically feasible to join given BLDC Motor with given Drive Electronics IC?

    Thanks. I am agreed to your comment about current sensing. However, if you look at the motor datasheet, how can I directly input the output of hall sensor into the FPGA without converting it to suitable voltage format for FPGA?

    moved- FPGA based control of BLDC Motor (BLDC , FPGA , ADC , IGBT , MOSFET , 3 Phase)

    I appreciate your input and I am thankful for the wise words. The matter is that this is the first time that I am dealing with HALL EFFECT SENSORS. In the datasheet of the motor, it is given as green VHall 4.5 ... 24 VDC blue GND red/grey Hall sensor 1 black/grey Hall sensor 2 white/grey Hall...

    Respected All Readers and Electronics Experts, Hello and a Good Day to all of you. Its my 4th or 5th post on EDA Forum ever since I joined it. Fortunately, I always found excellent solutions to my queries, hence my experience here has been excellent and I hope for the same this time again...
