    • e-bike Fiber Road Inc.
    • 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
    • | 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
    • | 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 )
    • 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
    • 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)
    • Maximizing drive performance 1.2. BLDC motor
      • System Configuration
    • Maximizing drive performance Motor & Controller Specification – 36V version (VM385 ) Item Voltage Current Torque Revolution Input Power Output Power Efficiency Unit [Vdc] [A] [N.m] [RPM] [W] [W] [%] Max.
