What does the new electric car's full-disk motor mean? What's the difference between brushless motor and current motor?
First of all, the structural composition is different.
1. Full-disc motor: mainly composed of driving wheel and motor.
2. Brushless motor: It is mainly composed of motor body and driver.
Second, the advantages are different.
1. Full-disc motor: long service life, large torque, and can adapt to any complicated road conditions. This motor combines the driving wheel and the motor into one, which is not only beautiful and elegant in appearance, but also has more than three times the torque and twice the service life of the ordinary brushless motor.
2. Brushless motor: The operation efficiency, low-speed torque and speed accuracy of brushless DC motor are better than any frequency converter with control technology, which deserves the attention of the industry.
Third, the characteristics are different.
1. Full-disk motor: Full-disk motor is made of new permanent magnet materials, with the largest magnetic energy per unit volume, stronger power and longer driving range.
2. Brushless motor: electronic commutation is realized by using semiconductor switching devices, that is, electronic switching devices are used to replace traditional contact commutators and brushes.
