System specification:

    Motors have special dual-stator structure, constituting automatic variable torque system with the special driver. According to the vehicles situation like climbing, starting, low speed and high speed,the system works in single-stator or dual-stator state automatically. Motor gives appropriate torque to make the dynamic performance adjust to the requirement. No longer need gearbox, avoid high current discharging, save energy, improve the travel distance, extend battery life.Brushless motor structure; no spark. No longer need to change the carbon brush. No carbon brush loss. Compact structure, high overload ability, long service life.Motor rotor has rare-earth permanent magnetic field,Do not need battery energy for excitation(A brush dc motor or an ac motor needs),saving energy. Generating effect is good when vehicle braking. Well energy feedback effect and electric braking effect.The systemworking principle: The drive timely checks the motor rotor position; the stator commutes according to the motor rotor position. The motor stator windings give current bringing positive torque which makes the motor run. The drive changes the duty cycle of the power semiconductors; the current changes; the motor torque changes; and the motor speed changes.Outstanding load characteristics,good low speed peformance,high starting torque,small starting current, preventing high current discharging of the battery, according to the discharging characteristics of the battery,adapting to the needs of vehicle frequent startup. The battery life can be extended by 50%,The driving distance can be prolonged about 30% ~ 50% once charged.The motor is equipped with excellent special motor drive, using high performance imported power module and control chip, using industrial components. The operating temperature is from -20°C to 60 °C. Reliable performance. Drive has stepless speed regulation, forward and backward operation, braking energy feedback. Multiple protections suchas overload, overheating, overvoltage and undervoltage. Output speed signal.The motor can work efficiently through the whole speed range, which has improved a lot comparing with the brush DC motor and AC frequency conversion motor( having high efficiency around rated point).Motors and drives are cooled by air or water. Low temperature. Motor adopts imported oil-contain bearings. Maintenance free, high reliability and long life. Motor is horizontal type. Motor could have raised front edge cover, dual shaft, spline shaft. The voltage, speed and power can be customized.
