摘要

本文主旨為研製無刷直流馬達控制晶片，傳統無刷直流馬達控制常使用微處理器或數位訊號處理器和各種控制方法來實現馬達控制，然而這些方法須耗費許多開發時間與人力成本。另外現有之馬達煞車是以煞車皮摩擦機構，但這種方法會造成摩擦之熱源損耗，且須定期更換煞車片等缺點。針對上述問題，本文提出具有電能回收煞車功能之無刷直流馬達控制晶片之設計，以降低開發時間、人力與成本。並利用無刷直流馬達驅動電路本身架構，不添加額外元件，設計煞車控制法則，達到無刷直流馬達再生式電能回收煞車。最後使用FPGA硬體整合及驗證無刷直流馬達驅動與煞車控制功能，並設計成積體電路控制晶片。

The purpose of this thesis is to design the control chip for Brushless Direct Current Motor. Conventionally micro-processors, digital signal processors and a variety of control methods are used for brushless DC motor control. However, these methods require a lot of development time, manpower and cost. The brake skin is used for motor braking, but this method will cause brake skin friction shortcomings resulting in heat energy loss and regular brake skin changes. This paper proposes a brushless DC motor drive integrated circuit with energy recovery to reduce the development time, manpower and cost. The brushless DC motor drive circuit architecture does not require additional components. The brake control law is designed to achieve braking regenerative energy recovery. FPGA hardware is used to integrate and verify the drive and braking control function of the brushless DC motor, which is designed into an integrated circuit control chip.
