This is a solution for three-phase brushless DC motor inverter control (vector control, 120-degree energization control) using a microcontroller (MCU).
Configuration
RX family
- Renesas Evaluation System for BLDC Motor (RTK0EMX270S00020BJ)
- Renesas 24V Motor Control Evaluation System for RX23T (RSSK: RTK0EM0006S01212BJ)
- CPU card (The RX23T CPU card is shipped with the RSSK. You will need to prepare another appropriate CPU card if you want to use a different microcontroller. Please refer to here for the model numbers.))
RL family
- Renesas24V Motor Control Evaluation System for RX23T (RSSK: RTK0EM0006S01212BJ)
- CPU card (You will need to prepare another appropriate CPU card if you want to use a different microcontroller. Please refer to here for the model numbers.)
※For the RL family, purchase and connect the RL family CPU card to the inverter board of the above 24V Motor Control Evaluation System for RX23T.
RA family
※When you use the RA6T1 CPU card and need an additional inverter board, use the Renesas Evaluation System for BLDC Motor (RTK0EMX270S00020BJ).
