Overview
Description
The RAJ306102 Renesas Solution Starter Kit (RTK0EML2J0S00020BJ) is used for evaluating a BLDC motor system using the RAJ306102 general-purpose motor control IC. RAJ306102 combines a smart gate driver (RAA306012) and an MCU (RL78/G1F) in a single package. It consists of a board with RAJ306102 mounted, a small 24V motor, and a connecting cable.
RAJ306102 is initially equipped with sample code for 120-degree conducting control using Hall sensors, and basic evaluation of motor control can be performed simply by connecting a 24V DC power supply and the attached motor. The integrated MCU operating voltage is selectable 3.3V or 5V. In addition, it is possible to connect and evaluate a motor and MOSFET prepared by the user.
BLDC motors have different control requirements than standard brush motors. Refer to our BLDC Motor Control Algorithms page for additional information and guidelines.
Features
- Easy to start motor control evaluation with RAJ306102
- Reference firmware has already been written on the RAJ306102. By connecting the attached small motor to the board and supplying power, evaluation can be started immediately.
- High expandability and operability via a small board (size: 140mm × 180mm)
- The board is small and easy to operate, and switches, potentiometers, LEDs, and thermistors are mounted, their functions can be used by using the user program.
- Connectable to the external MOSFET board
- By setting the selection resistors, it is possible to select mounted MOSFET and external MOSFET.
- Various sample code is available for basic motor drive
- Sample code of basic control required for BLDC motor control can be downloaded from the website.
- Sensorless 120-degree conducting control
- 120-degree conducting control using Hall sensors
- Sample code of basic control required for BLDC motor control can be downloaded from the website.
- Renesas Motor Workbench support (PC tool for waveform display)
- Renesas Motor Workbench is a tool for monitoring and changing global variables in operation from a PC.
