Driving a three-phase BLDC/PMSM motor requires varying degrees of intelligence to ensure the correct magnetization sequence is successfully generated. By using a microcontroller, motor drive designers...
1. If the MCU has a serial port peripheral, plus a level conversion chip, such as MAX232, SP3485, it is the RS232 and RS485 interface. 2. RS485 uses differential signal negative logic, +2~+6V represen...
