DESCRIPTION
OM9313SF, OM9314SF, OM9315SF provide full-featured, versatile `smart-power' electronics integrating 3-phase commutation, control, power outputs delta connected brushless (BLDC) motors. Only Hall effect sensors rotational directional signals necessary complete essential motor electronics. internal regulator (optional connection) permits single supply operation, simplifies design `stand-alone', single supply motor control electronics. three operating voltage ranges afford solutions variety systems needs, customizing operating voltage range accommodated. Analog and/or speed control readily implemented with external components. Custom modules allow integrating specific values passive speed control current sensing components. These `turn-key', fully tested hybrids, essentially, constitute BLDC motion control `system' within single package. They provide values performance, reliability, simplicity, versatility many fractional horsepower 3-phase motors. Both industrial hermetic MIL-rated versions available; circuitry electrically isolated from package.
