Brushless direct current (dc) knowledge analysis

With the development of the microprocessor technology and high switching frequency, low power consumption application of new power electronic devices, and control methods of optimization, and low cost, high magnetic energy level of the occurrence of permanent magnetic material, brushless dc motor controller emerged. Brushless dc motor controller is compared to the traditional dc motor controller, it keeps the good performance of speed adjustment, and it has no sliding contact and commutation spark, high reliability, long service life and low noise etc. So it can be used in aerospace, nc machine tools, robots, electric cars, computer peripherals, and other applications. To sum up, whether you for brushless dc motor controller to understand somewhat.
