System specification
●Motors 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 automatically work in single-stator or dual-stator state. 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 sparkNo longer need to change the carbon brushEliminate the loss of carbon brushCompact structureHigh overload ability, long service life
●Motor rotor with rare-earth permanent magnetic field
Do not need to absorb battery energy excitationA brush dc motor or ac motor need),saving energygenerating effect is good when vehicle brakingEnergy feedback effect is goodElectric braking effect is good
●The system’s working principle
Driver timely collect information of motor rotor positionthe phase is changed according to the motor rotor position. The motor stator windings give current to produce positive torque which make the motor runThe speed-control signals change the duty cycle of the power device. So the current changes, the motor torque changes, and the motor speed changes.
●Outstanding load characteristics
good low speed peformancehigh starting torquesmall starting current, preventing high current discharging of the battery, according to the discharging characteristics of the batteryadapting to the needs of vehicle frequent startup. The battery life can be extended by 50%The driving distance can be prolonged about 30% ~ 50% when charged.
●Equipped with excellent special motor driver
Using high-performance imported power module and control chipUsing industrial components. Operating temperature is -20 degrees; military level requirement can reach - 40 degrees; reliable performance. Driver with stepless speedPositive &negative control operationBraking energy feedback; Multiple overload overheating protectionover-voltage protectionunder-voltage protectionSpeed signalvoltage and curent output.
●Motor in the whole speed range can operate high efficiently. It has greatly improved comparing with a brush dc motor, ac frequency conversion motor

●Motors and drives are cooled by air or water. Low temperature. Motor adopts imported oil bearing
Free maintenanceHigh reliabilityLong life
1.        Motor is horizontal type. Motor could have raised front edge cover, biaxial stretchSpline. The voltage, speed and power can be customized.
