PWM MANAGEMENT FOR 3-PHASE BLDC MOTOR DRIVES USING THE ST7MC

9 CONCLUSION

As seen in this document, the ST7MC with the features of its dedicated peripheral offers a lot

of combinations for the PWM management when driving a BLDC motor. Thanks to a high

hardware integration (both digital and analog) and a high flexibility of configuration through

dedicated registers, the PWM management can be fine-tuned and optimized to reach and

maintain the best efficiency of the motor whatever the control method.

This flexibility combined with the fact that the ST7MC family comes with the 8-bit ST7 core, a

very well known and stable core, and is offered in a wide range of packages (8Kbytes to

60Kbytes memory size Flash/ROM and from 32 pins to 80 pins) allow this part to be suitable

for all the motor control applications requiring a scalar motor control.

The associated development kit, ST7MC-KIT/BLDC, that is provided with full C libraries soft-

ware and reference hardware design allows you to get his application up and running in a min-

imum amount of time for a better “time to market”.

In conclusion, a good time to market, high performances and cost savings are the keys of a

successful design done with the ST7MC.
