how to run BLDC motor by means of Dspace hardware

Hi I've got a little problem with running a BLDC three-phase motor via Dspace ds3011. Motor contain three hall sensors. So I switched on signals hall to three analog-digital input channels on dspace board. Then I've been converted this signals to logical 1 and 0 in Simulink. Could you explain me what next step by step. How to create a logical board, which interpret whose phase have to be supplied. This is my first step in simulink and i don't know a lot. Best regards Sebastian

Well mr.sebastian, why you use ADC for reading hall information instant of DIO, use DIO then you gat better faster performance then compared with ADC. Next you need to creat your six stepping secquence as per the hall information, what are the switches should be on. then decode the signals from hall sensor as per your sequence using decoder ( you need to create your own decoder as per you motor), then send these signals to PWM generator. i too working on this area. contact me if you want more information through [e-mail]
