Motor Control for Power Tools

This motor control design is intended for power tools. The power source (battery or mains power supply) is not included in this proposal and is represented here as a simple battery pack. For reference, a high voltage solution (48V) is demonstrated using a high-performance Arm^® Cortex^®-M4 based MCU. This MCU features specific PWM timers for 3-phase motor control, including a floating point unit (FPU) to enhance algorithm performance.

System Benefits:

• High integration MCU with motor control, ADC, and DAC features
• Discrete design includes an embedded LDO for MCU power supply, powered by the high motor voltage rail
