BLDC Motor Controller V3
A third BLDC motor controller completely redesigned using EPC23102 GaN power stages and high-bandwidth hall-effect current sensors aiming to operate at higher voltages (48-65V) and be able to efficiently control low-electrical-time-constant motors in a small form factor
Specifications & Design Targets:
- 48V (max 60V) operating voltage
- 500kHz switching frequency
- Fully ceramic bulk capacitance
- Two-phase inline current sensing with 1MHz bandwidth
- RS485 interface for commutation encoder
- Hall sensor/GPIO pins (48V bus fault protected)
- External thermistor for motor overtemp protection
- CAN for control and telemetry
- Half-credit-card form factor
- XT60 for power and MR60 for phase connections
