Along with the times, technology in transportation sector continues to develop rapidly. This is marked by emergence of vehicles that are modern and practical use. One example an electric bicycle. bikes a new option development alternative transportation. Because these problems, tool was made can turn ordinary bicycle into So owners simply easily bicycles bikes. uses battery as its energy source...

ABSTRAK Penggunaan gerobak lsitrik untuk meningkatkan jangkauan dagangan bagi pelaku usaha keliling saat ini menjadi hal yang patut mendapat perhatian di karena era modern seperti sangat erat kaitannya dengan kendaraan berbasis listrik. Banyak jenis motor listrik gunakan sebagai penggerak listrik, namun pada penelitian penulis mencoba menggunakan brushless DC tersebut. Setelah melalui tahapan d...

Although brush type DC machinery has lost market share over the years to its brushless counterparts, it still maintains a significant presence in the automotive, aerospace, power tool, and home appliance industries. Especially in automotive and aerospace power system applications, early detection of brush type DC machine faults will help to avoid problematic system failures, decrease maintenanc...

Brushless DC motors (BLDC) are widely used in industrial areas. The BLDC motors are driven either by indirect ACAC converters or by direct AC-AC converters. Direct AC-AC converters i.e. matrix converters are used in this paper to drive the three phase BLDC motor and it eliminates the bulky DC link energy storage element. A matrix converter converts the AC power supply to an AC voltage of variab...

This paper proposes a capacitance estimation method of the dc-link capacitor for brushless DC motor (BLDCM) drive systems. In order to estimate the dc-link capacitance, the BLDCM is operated in quadrant-II or -IV among four-quadrant operation. Quadrant-II and -IV are called reverse braking and forward braking, respectively. During the braking operation of the BLDCM, the capacitor is charged by ...
