Nisshinbo Micro Devices has launched the NA7200BE series 3-Phase BLDC Motor Controller IC intended for general purposes such as fan and other small BLDC motors. The NA7200BE offers a range of ...

They’ve taken the field-oriented control algorithm and encapsulated it into a compact Arduino library, added a host of examples, and minted a stackable BLDC motor control shield to boot.

The TB9062FNG pre-driver can control BLDC motors using only a simple pulse-width modulation (PWM) input, without the need for any high-performance microcontrollers (MCUs) and software.

The source for their BLDC motor controller is available through their GitLab page. For more information on the parent project that uses the BLDC driver, be sure to check out their work on a ...

However, drive circuit complexity and cost have limited their adoption. The good news is that recent developments in semiconductor drive circuits are making BLDC motors more desirable.
