Brushless DC motor controller board

[CKD]

Dạo một vòng tìm hiểu về Brushless DC (BLDC) motor.. phát hiện ra thằng này thấy hay hay... Có thể dựa theo để phát triển thành BLDC servo cũng nên

Bullet points:

• Can drive brushed and brushless (3-phase) DC motors
• 15~30V input voltage
• Single-supply operation (onboard LT3470 SMPS)
• 10+A per-phase current handling (Si4456DY MOSFETs)
• Low and high-side N-Channel MOSFETs (driven by LM5101 gate drivers)
• Per-phase current sensing (sensed via AD8216 difference amplifiers)
• Per-phase voltage sensing
• Sensored (hall-effect or rotary encoder) or sensorless (back-EMF measuring) operation
• Cortex-M3 32-bit ARM CPU (STM32)
• CAN-bus transceiver (MCP2551)
• RS-422 full-duplex transceiver (DS89C21)
