Motor Control for Power Tools
Renesas’ motor control reference design has PWM timers for three-phase control and an FPU to enhance algorithm performance
For this winning combination reference design, Renesas chooses a high voltage solution (48 V) that features the high-performance Arm®-M4 based RA6M3 MCU. It has specific PWM timers for three-phase motor control and a floating point unit (FPU) to enhance algorithm performance.
This block diagram shows a setup that includes an embedded power supply for the MCU (3.3 V) and MOSFET half-bridge drivers (12 V).
The power source (battery or main power supply) is not part of this proposal and is represented here as a simple battery pack.
