BLDC motor controller Specification

  • BLDC Motor Controller Hardware General Description:

    • Operating voltage range: 12V - 44V.
    • Built-in bulk capacitance (200µF) for stable motor control and power supply. External precharge circuit required when connecting multiple boards.
    • Multiple voltage rails (3.3V, 3.3VA, 5V, 12V) for stable power supply.
    • Field-Oriented Control (FOC) for BLDC motor operation.
    • Current handling: 30A continuous, 100A peak.
    • Compatible with multiple BLDC motor types.
    • Supports RS485 and CAN communication protocols.
    • Hall sensors for closed-loop control.
    • Temperature monitoring for motor and MOSFETs.
    • Motor cooling capability.
