  1. 1. e-bike Fiber Road Inc.
  2. 2. Project VM 1. Introduction 2. BLDC Motor 2. Controller 3. Battery New Performance 1. Smart Driving Control 2. Long Drive Distance 2. Heavy Weight on Board
  3. 3. | Corporate Identity Value - The paradigm of human-centric - Space-time of the Revolution - Convergence and Integration in industrial tow Technology - Power Brain - Low-carbon, high-efficiency -GT + IT + CT + Services Innovation - Eco friendly means of transportation -Wellbeing lifestyle - Smart grid
  4. 4. | Business Domain Smart Bike NEV/Recreational EV SW/Service Controller -E-bike -Smart bike kits -E-Scooter -Tricycle NEV -Electric car (Public welfare NEV ) -Recreational EV (Park, Kids, Rail EV) -Real time EVMS (Vehicle management -LBS based EVIS (Local tourist information) -Personalized Driver System -IGBT -BMS (Battery Management System )
  5. 5. e- bike | New Technologies USB Charge System Digital Control Electric Semiconductor (IGBT) Power & Smart Battery Maximizing drive performance (Advanced BLCD motor applied ) Motor of designs using the wheel hub space. Personalized Driver System
  6. 6. Maximizing drive performance 1.1. BLDC motor * Technological Merit from VM Motor - Higher Torque, Speed from Lower to High Band. - Easier Electric Driving Maintenance, Make Longer Lifespan of Device, Remarkably Decrease Electronic also Mechanical Noise.   - Eliminate Disadvantageous of Conventional Electric Resistance Types in Controlling Method such as Sliding Abrasive Torque, Loose Contact due to Abrasion also Corrosion, Poor Operation. - Possible to Match in Switching Electronic Circuit with Next Generation Semiconductor.   - Controlling Efficiently by Smart Response (Improve Efficiency 20-30% to Existing Products)
  7. 7. Maximizing drive performance 1.2. BLDC motor <ul><li>System Configuration </li></ul>
