  1. 直流无刷电机驱动方案介绍 朱益杉 2018年5月24日

  2. 内容 • 专注领域 • 产品组合及介绍 • 开发及生产工具支持 • Q&A

  3. 专注领域 • 风机应用 空气净化器 空调室内机风扇 空调室外机风扇 除湿机 吊扇 … 油烟机 燃气热水气强排扇 落地扇 • 水泵应用 … 洗碗机洗涤泵 一般水泵 智能马桶 逆渗透纯水

  4. 三相直流无刷电机驱动系统 RM02N60 RM05N60 Power Converter RT7300A (for<200W) Power Device BCM PFC RT707x Two-in-one RT8409 Sensorless or Hall-sensor Standby Power 3-PhaseGate Driver RT7100 Motor Controller RT705x All-in-one

  5. 三相电机控制器—RT7100 • ARM Cortex M0 (60MHz) + Control Blocks • Control algorithm: Sensorless (or 1 Hall element) Sine-wave FOC • Embedded motor control library • UL-IEC60730 certificated (No. E478780) (60MHz) TSSOP-28 RT7100

  6. 无感测的主要优点 Hall element or Hall sensor

  7. UL IEC-60730安规认证 IEC-60730 Library System safety check (OC, OT) Risk of fire System FMEA • Benefits: • Assure operation safety under firmware fault conditions. • Shorten certificate application process. • Cost saving in certificate application. • A guarantee of quality and safety to user and customer. Micro-electronics check (PC, ADC, registers…etc.)

  8. 低转速时的相电流波形 High performance sine-wave FOC Solution A RT7100 still sine-wave waveform distortion Solution B • Sine-wave at low speed operation • Lower noise & vibration waveform distortion 8 * These waveforms are measured at low speed (150RPM) with the same pedestal fan.

  9. 600V“二合一”方案—RT7075 RM02N60 Integrate MCM Motor controller & Gate driver LQFP 7x7-48 Motor Control LIB IEC 60730 LIB Micro Electronic Check Sensor-less FOC Startup Strategy Over Current Check Current Control Lock Rotor Check Speed Control UL IEC-60730 certificated (No. E478780) RT7075

  10. 三相直流无刷电机驱动产品 * MP: Mass production ; DVP: Developing

  11. 600V“三合一”方案—RT7053 RT7053 WQFN 13x13-38

  12. 三合一产品的效益 • Reduce device count • Integrate AC/DC & motor driver units to a signal PCB • Easy design & cost effective Motor Driver IPM RT7053 L71 x W71 (mm) + AC/DC L50 x W43 (mm) L71 x W71 (mm)

  13. 600V单相门驱动产品

  14. 开发工具—电机调适板支持 AC/DC Board Motor tuning EVB Communication Kit Ke Board Programming Kit 14

  15. 开发工具—软件支持 Adaptive Motor Control Development System • Complete motor control library • Startup strategy • Debug support • Firmware example • Lower design complexity • Shorten motor tuning process • Reduce development cycle

  16. 生产工具支持 IC Firmware (F/W) Programming Support & Service • On-line Isolated programming kit • Off- line programming kit • IC F/W re-programmable for assembled motors • IC F/W programmable for mass production On-line Isolated programming kit Off-line programming kit F/W re-programming by FG & VSP pins
