40W motor without a heat sink! Brushless motor driver for weighing conveyors.
【Issues / Results】 ■ I want to control 31 units collectively via serial communication. → Supports collective control of up to 31 units via RS485. ■ I want to control two types of 15W/40W motors from different manufacturers with a single circuit board. → Supports two types of motors with different conditions by parameter adjustment, with just a DSW switch. ■ I want to reduce heat generation. → Adopts NchFET three-phase bridge circuit. Built-in ideal diode circuit. Eliminates the need for a heat sink due to improved efficiency. ■ I want to make it more compact. → Can be stacked at half the height. Eliminates the need for a heat sink due to improved efficiency. Sized to fit a business card. ■ I want to improve controllability. → Improved controllability through a unique control algorithm. Built-in regenerative circuit with four-quadrant rectangular wave drive. ■ I want to reduce costs. → Cost reduction for the system as heat dissipation components like fans become unnecessary due to improved efficiency. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Despite being located in the remote Wakayama Prefecture, we provide technical support to strong venture companies that aim to create new value in the domestic market and among leading manufacturers. <Business Areas> 〇 Analog and Power Electronics Circuit Design If you have challenges related to the efficiency of analog circuits (such as power supplies, motors, pressure sensing, or feedback control), stability or improvement of output values, or noise countermeasures, please feel free to consult with us. We are also skilled in tuning after the production of actual devices. 〇 PCB Design, CAD, Verification, and Documentation With a strong foundation in electronic circuit knowledge, we have extensive experience in PCB design and CAD (OrCAD/CR8000). We also have a track record in verification and documentation, including responses to FMEA and FTP. Regarding verification documents, we actively provide comparative data before and after tuning and conduct reviews (explanations) through meetings via web or other means. Additionally, we are flexible in providing partial support for verification, drawing checks, tuning, and other areas, so please feel free to reach out to us.
