12V Small Motor Solution

Renesas provides a best-in-class practical BLDC motor control system development kit for pumps and fans. Users can select between the RL78/F24 and RH850/F1KM-S1 kits depending on the application needs. Implement three control methods (sensorless field oriented control (FOC) 3 shunt, sensorless FOC 1 shunt, trapezoidal) using RL78/F24 peripherals, or implement high-speed sensorless FOC for applications with high CPU utilization using the high-performance RH850/F1KM-S1.

System Benefits​:

• Easy to Start
  • Complete reference design (circuit diagram, PCB design) including characteristic data
  • RL78/F24 kit provides three types of sample control software (FOC 3-/1-shunt, trapezoidal)
  • RH850/F1KM-S1 provides motor control software and motor calibration tool for adjusting motor parameters
• Design Flexibility
  • Available sample hardware and software to support motor control development
  • Reference design capable of driving motors up to 100W
• Cost Efficiency  
  • Small board size, designed to incorporate into the motor housing (60mm × 56mm)
  • RL78/F24 kit enables sensorless FOC control (1-shunt) using a new timer function (asymmetric PWM output), and overcurrent detection with a built-in comparator circuit
