Beschreibung
This TI Design is a 3-Phase Brushless DC Motor Drive designed to operate in 48-V automotive applications. The board is designed to drive motors in the 1-kW range and can handle currents up to 30- A. The design includes analog circuits working in conjunction with a C2000 LaunchPad™ to spin a 3- Phase BLDC motor without the need for position feedback from Hall Effect sensors or quadrature encoder.
Eigenschaften
- Speed Control of 3-Phase Brushless DC (BLDC) Motors With no Position Sensors Needed
- Phase Voltage and Current Sensing Scaled and Filtered Feedback for Control of 3-Phase Power
- Operates Over Wide Range of Voltages From 48-V Battery System
- Protection Against Overvoltage, Undervoltage, Overtemperature, Overcurrent, and Transient Faults
- Reverse Polarity Protection on 12-V Battery
- Isolated CAN Interface Connects to Automotive Networks on 12-V Battery System
- Critical Components Fit in a 5-inch Diameter Circular PCB
- Components Selected for Automotive Temperature and Quality
- Test Points Provide Easy Access to Key Motor Signals
Typische Anwendungen
- Water Pump, eTurbo, Radiator Fan, HVAC Blower, Oil Pump
