how to distinguish between the motor vehicle electric balance of advantages and disadvantages
Balanced car balance car motors like "legs", the same group 4400MAH lithium battery, high-quality good efficiency motors can run 15-20 km, so buy electric car assembly must pay attention to select high-quality accessories. How can we distinguish between motor and cons?
Since the motor is sealed, if it's good or bad judgment fundamentally, it needs some external tools, such as words table. In addition to the help of professional tool, you can also be judged from the appearance of materials and general performance. The above methods can simply be attributed to: a second look at the three touch Tetra Detector.
A: Listen power. When commissioning, consumers can load plenty of starting power if power is not likely to cut corners in plenty on the motor windings.
Second look: see enclosure. The outer plating work to do good motor generally look more bright. Then you can see the motor identification, generally larger manufacturers are marked with wheels codes and abbreviations brand above production date, which is a manifestation of the brand quality.
Three touch: touch temperature. After the motor stops can hand to sense the temperature of the motor, the lower the temperature, the better the motor heat dissipation, the better the performance.
Tetra Detector: sense resistor. 1, the detection phase AC motor is good or bad shake table, 500V shake table to shake the three terminal lines on the insulation resistance of the motor housing, in Europe more than it shows no 0.5M short to ground. 2, multimeter test: test A / B / C three phases of the resistance, are equal. The larger the difference between the value of the motor performance worse. And the greater the motor power, the smaller the resistance! But not the three-phase is 0 Euro, except as above 50KW motor particularly large, but the current electric vehicle applications can say no.

As shown above, the balance of the motor vehicle is in-wheel motor, also known as permanent magnet brushless motor. The wheels, tires, stator and cover several major components. Magnet attached to the hub, magnet height, size and temperature under magnetic degaussing ratio on the dynamic performance of the motor; stator consists of silicon and copper wire is made, generally using 0.51mm diameter of the copper wire, winding density, height, number of turns, also determines the dynamic performance of the motor.
Detection balanced car motor fact, the best way is installed after the experience, you can choose installed after the road test, the road on a flat road can feel the smoothness of the motor, motor good flat road running smooth, no bumps sense; turn test, Sharp love to see the stability of the motor; climbing test, to find there is a slope on the road, how the ability to look and feel of climbing during downhill.
