DESCRIPTION
The OMC510 is a DSP-based three-phase brushless DC motor controller intended to replace the analog controller to improve system integration, efficiency, flexibility, and reliability while reducing the overall system cost. The standard OMC510 is configured for commutation via Hall effect sensor feedback. In this configuration, the Hall effect sensor outputs provide discrete absolute rotor position for commutation. The Hall effect sensor outputs are fed into the control port, level shifted onboard from 15V to 5V, then fed directly into the DSP. Based on this information, velocity is determined. Alternatively, the OMC510 can be configured for commutation via sensorless control. Three resistor divider networks are provided onboard for back EMF measurements. In this configuration, the inactive winding is used to measure the back EMF, and based on these measurements, estimates of position and velocity are derived. Consult the factory for details.

FEATURES / BENEFITS
• Embedded Motor Control DSP (ADMCF328) improves higher level system integration and flexibility
• 7A phase current (cycle-by-cycle current limit)
• Hall Effect sensor based; sensorless control optional for improved reliability
• Logic supplies (+15V/+5V) generated onboard, eliminating external parts
• Serial port for isolated RS-232 interface allows system level control
• Direction and velocity control
• 2.5 Inch diameter to fit inside motor housing

APPLICATIONS
• Fans
• Pumps
• Compressors
