Controlling 4 DC motors and generate PWM

[poorabedi]

hi all

i have 4 DC motors with shaft encoder (up 1MHz).

i need a device for reading signals from shaft encoder and do many algorithm in real time (less 1ms) then produce 4 PWM signal for controlling device.

please guide me for that.

with regard.

Hello,

You should be able to do this through the use of a real time controller and an FPGA. If you would like, you can call into National Instruments (1-866-ASK-MYNI) and one of our account representatives can pinpoint what devices and/or software would be needed to accomplish your desired tasks.

thanks Jordan

my DC motor need 12 Volte and encoder signal is 5 volte.

i saw many sb-RIO device that have 3.3v io line.

so what RIO device is suitable?

We would need a few more details, but you should be able to accomplish this through the use of one of our cRIO devices and an NI 9411 module.
