Step-by-step guide to brushless DC motor control system design

Whether you’re developing motor control systems for consumer electronics, industrial automation, or e-mobility, EZ-PD™ PMG1 provides the flexibility and power you need: it is not just a high-voltage USB-C Power Delivery microcontroller; it’s a comprehensive solution for motor control. 

The integration of EZ-PD™ PMG1 into motor control designs is straightforward and efficient thanks to the ModusToolbox™ software, its dedicated SDK and related tools, which significantly shorten development and, thus, time-to-market.

Brushless DC motors

Why choose EZ-PD™ PMG1 for brushless DC motors:

  • Sensorless operation: implement efficient control of brushless DC motors with the MCU’s sensorless operation capabilities
  • High efficiency: optimize power and performance with the MCU’s support for high-power applications up to 140 W

Designing a BLDC motor control system with EZ-PD™ PMG1-S3
In this demonstration, we will show how to implement a USB PD-powered sensorless brushless DC motor control system using CY7113 EZ-PD™ PMG1-S3 prototyping board. The complete procedures are presented in the application note "USB PD sensorless brushless DC (BLDC) motor controller using EZ-PD™ PMG1-S3 MCU", while the firmware discussed is provided as a code example within ModusToolbox™ SDK.

Brushed DC motors

The robust design and advanced features of EZ-PD™ PMG1 make it an ideal solution also for brushed DC motors, offering:

  • Precise control: achieve fine-tuned control over your brushed DC motors with EZ-PD™ PMG1’s advanced PWM capabilities
  • Integrated diagnostics: monitor motor health and performance with built-in diagnostic features
