24V Brushless DC (BLDC) Motor Sine Wave Drive for Air Purifier Fan
This reference design is an affordable, small form factor (SFF), three-phase sinusoidal motor drive for brushless DC (BLDC) motors, delivering up to 50W at 24V. This board accepts 24V input and provides three motor outputs to drive BLDC motors sinusoidally. After accepting the speed command through the IR (infrared) sensor, the speed loop is closed externally using a microcontroller (MCU) (MSP430G2303 in this design).

Capable of driving brushless DC (BLDC) motors with sinusoidal commutation as a 50W, 24V driver
The role of MSP430G2303 is to accept IR input and close the external speed loop
The DRV10983 uses a proprietary sensorless control scheme to provide continuous sinusoidal drive, significantly reducing the pure tones typically generated during commutation
Powers internal and external circuits (TI MSP430â„¢ MCU in this design) by efficiently reducing the supply voltage to 3.3V with an integrated buck/linear regulator

The stepper motor driver is also called EasyDriver. The EasyDriver can provide about 750mA per phase (1.5A total for both poles) for the two-stage stepper motor. It defaults to 8 step subdivision mode (so if your motor is 200 steps per revolution, it defaults to 1600 steps per revolution when you use EasyDriver), more subdivision modes can be done by grounding both pins MS1 or MS2 set up. This is a subdivision circuit breaker based on the AllegroA3967 driver chip. For full specifications of this design, please consult the parameter sheet for the A3967. Its maximum current per phase is from 150mA to 750mA. The maximum drive voltage that can be used is about 30V, including the onboard 5V regulator, so only one power supply is required. Good quality and cheap, this thing is only a dozen bucks, which is cheaper than making your own circuit boards.
Stepper motor driver design features:
·A3967 Microstepping Driver
MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
Compatible with 4, 6, and 8 wire stepper motors of any voltage
·Adjustable current control from 150mA/phase to 700mA/phase
·Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds

Design experience
The driver board of the smart car has three main functional parts: boost, half-bridge or full-bridge control, and mos switch. After understanding these three parts, you can combine and design circuits at will. For example, I can use LM2577, mc34063, LMR62014, etc. for boosting, and HIP4082 for the controller, no problem. In addition, when wiring, the most important thing to pay attention to is the line width, because it is only driven by the motor, and the current passing through is relatively large, so the motor current line needs to go wide, 120 mil is not too much, you can also open the window and apply thick tin.
