System specification
¡ñMotors have special dual-stator structure, constituting automatic variable torque system with the special driver. According to the vehicle¡¯s 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.
¡ñBrushless motor structure; no spark£®No longer need to change the carbon brush. No carbon brush loss. Compact structure, high overload ability, long service life
¡ñMotor 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. Energy feedback effect is good£¬Electric braking effect is good.
¡ñThe system¡¯s working principle£ºThe 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.
¡ñOutstanding 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.
¡ñThe 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¡æ to 60 ¡æ. 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.
¡ñThe 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).
¡ñMotors and drives are cooled by air or water. Low temperature. Motor adopts imported oil-contain bearings. Maintenance free, high reliability and long life.
¡ñMotor could be horizontal or vertical type. Motor could have raised front edge cover, dual shaft, spline shaft. The voltage, speed and power can be customized.
