The article presents the working principles and construction of a brushless DC motor. The BLDC motor control methods were discussed, including the division into methods using sensors for determining the rotor position and sensorless methods with an example of implementing BLDC motor control using microcontrollers. High efficiency and high durability as well as falling prices of electronic components and controllers cooperating with BLDC motors in recent years have caused a growing interest in this type of motors. The design of BLDC motors does not require the use of brushes, which in traditional brush motors supply voltage through the commutator to the rotor windings. Brushless motors are characterized by high efficiency, durability and reliability. The use of sensors in BLDC motor control systems increases the number of motor and commutator connections, thereby reducing the reliability of the drive system. For this reason, direct position and speed measurements are often abandoned for the use of sensorless control methods. DC brushless motors have various application areas, and due to their reliability and the ability to control speed, they are used, among others, in electric vehicles, medicine and industry.

In this thesis , the control strategy based on sensorless BLDCM(Brushless DC Motor) has been researched.A control system for BLDCM operating on ADSP-BF548 has been given. we focus on studying the control strategy of sensorless BLDC motor based on back-EMF detection, and present a control system for BLDC motor based on ADSP-BF548 special for motor control. The calculation method of back EMF in BLDC motor was deduced and the hardware circuit of line voltage detecting was designed. A pre-position starting tactics based on back EMF detection and a tactics of phase converting by postponing back-emf-zero-crossing detecting was designed. The signal wave was filtered by postponing back-emf-zero-crossing detecting when back-emf-zero-crossing had been detected. To release the phase delay caused by hardware filtering, a phase compensation algorithm has been designed. The PID adjusting algorithm and other strategy are designed in this program. Experimental results show that the control system has good speed adjusting performance and runs stably.

AbstrakKrisis bahan bakar fosil menjadi salah satu alasan pengembangan teknologi dalam bidang transportasi contohnya kereta listrik dan mobil listrik. Salah satu penggerak yang saat ini banyak digunakan pada kendaraan listrik adalah motor brushless DC (BLDC) yang memiliki efisiensi tinggi, hemat biaya perawatan dan pengaturan yang mudah. Pada umumnya penelitian yang dilakukan terkait dengan motor BLDC adalah tentang pengaturan kecepatan motor, pembebanan pada motor dan yang lainnya. Penelitian ini melakukan simulasi cara pengaturan kecepatan motor BLDC dengan beban yang diubah-ubah dengan menggunakan software PSIM (Power Simulator). Data yang diperoleh melalui simulasi dengan memberikan beban maksimum sebesar 20 Nm dan hasil perhitungan menunjukan bahwa motor BLDC dengan spesifikasi yang digunakan dapat berputar dengan baik pada kecepatan 1442,05 rpm dengan efisiensi sebesar 81,25 %. Jika  beban yang diberikan pada motor BLDC dinaikan menjadi 30 Nm maka kecepatan motor akan mengalami penurunan menjadi 1221,51 rpm dan efisiensi menjadi 78,34 %.Kata kunci: motor BLDC, Kecepatan motor, Beban, efisiensiAbstractThe fossil fuel crisis is one of the reasons for the development of technology in transportation, for example electric trains and electric cars.

The brushless DC motor (BLDC motor) drive is used in several high performance applications ranging from servos to traction drives, due to several distinct advantages such as high power density, high efficiency, fast response and maintenance free. BLDC motor is usually driven by hard switching PWM inverter, which normally has higher switching losses. In recent years, these are several soft switching inverters presented. But there are many disadvantages such as high device voltage stress and large DC link voltage ripple and so on. This paper presents a transformer based resonant dc link inverter for brushless dc motor. The modulation strategies can be classified into two kinds according to the turn-off sequence of the two switches of the pair of switches. Here, dc link voltage notches during chopping switches commutation for all switches working in zero voltage switching condition. The operating principle of soft switching and control scheme are presented. The proposed scheme is verified with the simulation and experimental results.

<p class="Abstract">Brushless DC motor (BLDC) is one type of electric motor that is widely used, especially in automotive systems. This motor is widely used as a driving force in electric vehicles. BLDC motor is chosen because it has the characteristics of high efficiency, reliability, and a wide speed range. Besides, BLDC motors require less maintenance and can operate quieter than DC motors. Even though it has many advantages, in its application the use of BLDC motors in electric vehicles is often less than optimal. The use of a conventional control system proportional integral derivative (PID) still has many weaknesses, especially in response to changes in load and track conditions. In this study, a control system was designed to regulate the speed of the BLDC motor, using a combination of Fuzzy and PID methods. Based on the results of the tests that have been done, the Fuzzy-PID control can provide better and more stable performance than using the conventional PI control.</p>
