Description

1. Great power: the maximum power of BS3 BLDCM which matches the complete set of buses is **0KW; it can supply the matching units to the luxurious electric bus of large size. 2. High-efficiency: the efficiency of **0KW is up to *7.2%.with the drop of load and voltage, 　the efficiency curve of BLDCM is basically flat and only slightly down.　When the load of AC frequency motor is *0%, the efficiency is only *9%. 3. Low noise: In design and production technology , low noise design and special technology are adopted to avoid harmonic noise. In addition, the modulation frequency is designed to be *5K, which is basically close to supersonic frequency. 4. Small size and light weight: BLDCM adopts water-cooled system. With optimum design, the power, torque, and flux density are high, thus the size of motor is small, and its weight is light. 5. Large output wheel base; with 1/2 of the rated speed, the startup and overload torque can be four times of the rated torque. With the speed reduction device of the body, the torque of the wheel base can be 6 to 7 times. 6. Good characteristics of low-voltage: BLDCM can work as usual under **0VDC of voltage, with the same external characteristics of other motors under **0VDC of rated voltage, thus the utilization rate of batteries is increased, and the endurance mileage of electric vehicles is extended. 7. The width of motor’s high-efficient part: when the system efficiency is *0%, it is *4% of high-efficient part. High efficiency and energy conservation are realized. 8. Stable performance of motor’s locked-rotor: the motor can still output 4 times of rated torque at a zero speed, The rotor is locked for one minute with 2 times of the torque; the elevated temperature of motor coil will not be more than *0 degrees; the current of the bus bar is only 1/*0 of the rated current. 9. No demagnetization; the technology of no demagnetization in normal conditions is a patent of our company.
