Various industrial equipment, such as screw-tightening machines and torque testers, need to control motor rotation while measuring torque. By inputting the torque measurement signal from the MCU equipped with a high-precision analog front end to the high-precision motor control solution for motors and performing feedback control, high-resolution torque control can be achieved with a simple configuration.

System Benefits:

  • High-precision torque measurement with the RX23E-A 32-bit MCU with its high-precision analog front end (AFE)
  • RX/RA T-series allows the combination of precision motor control and measurement in a simple configuration to realize high-resolution torque control
  • High-precision sensing is supported by low-noise, high-PSRR (Power Supply Rejection Ratio), stable high-quality power supply




  • Screw tightening machine
  • Torque tester
  • Torque actuator
