1600W Brushless DC Motor Driver Three-phase DC Hallless Motor Controller

1.Introduction:
This product is a drive module developed for non-inductive BLDC motors, the drive main control chip is SNR8503M, the core integrates a special circuit for inductive motor drive, the surrounding circuit is simple, the function is perfect, the volume is small, the debugging is simple, the drive efficiency is high, the application is flexible, and it is widely applicable.

SNR8503M is a 32-bit core MCU, which is easy to develop and debug. In order to facilitate users to quickly implement the drive non-inductive BLDC computer, and the software core algorithm layer has been completed, you only need to carry out secondary development on the basis of this software, and you can quickly complete product development.
