32-Bit BLDC EVB: MDF Series
✅ FOC (Field-Oriented Control)
✅ Six-Step (Square Wave) Control
✅ Sensored and Sensorless Control
✅ Rapid Motor Validation and Tuning
The board integrates the main controller, driver stage, power management, sensor interfaces, and debugging functions into a compact design, making it ideal for:
🔹 Motor control algorithm development
🔹 Driver circuit verification
🔹 Product prototyping
🔹 Educational and technical demonstrations
(*The image above shows the EVB with a P/N MOSFET driver architecture. An N/N MOSFET driver version is also available.)
1. Main Control Module
As the core control unit of the system, the MCU is responsible for:
• Receiving control commands
• Processing sensor signals
• Generating PWM waveforms
• Controlling motor speed and direction
Supporting components such as resistors, capacitors, and crystal oscillators provide stable clock generation, filtering, and reset functions to ensure reliable system operation.
2.Driver Module
The board integrates a three-phase P/N MOSFET driver architecture to effectively amplify PWM signals and drive BLDC motor windings.Additional integrated features include:
• Current sensing resistors
• Hall sensor interfaces
• Overcurrent protection mechanisms
These features enable easy implementation of closed-loop control and system protection functions.
*(An N/N MOSFET driver architecture version is also available.)
Consisting of voltage regulators, electrolytic capacitors, and filtering circuits, the power management module provides stable 12V and 5V power supplies, ensuring reliable operation under varying load conditions.
4. Debug Interface
Supports both J-Link and Megawin M-Link debugging tools for program downloading, emulation, and debugging, significantly improving development efficiency.
5. Configuration Interface
DIP switches, function buttons, and pin headers are provided for convenient mode selection, parameter adjustment, testing, and connection to external Hall sensors.
6. Pre-Driver Module
3. Factory-Tested and Ready to Run
Every MDF101A EVB undergoes comprehensive validation before shipment, including:
✔ Functional module testing
✔ Real motor load testing
✔ Self-diagnostic and self-test firmware programming
Users can simply power on the board and begin operation immediately.
For customers with limited motor tuning experience, Megawin Technology also provides professional FAE support and training services to help accelerate project implementation and shorten the learning curve.
4. Proven Applications of the MDF101A EVB
✅ Fans and Air-condition Systems✅ Water Pumps
✅ Power Tools
✅ High-speed Blowers and Hair dryers
✅ Lawn Mowers
Megawin Technology provides complete hardware and software reference materials, enabling customers to quickly validate and develop products using the MDF101A EVB together with their target motor, significantly reducing development time and cost.
