Motor Health Monitoring detects the motor health status with Renesas RE Family’s ultra-low current consumption, high-performance MCU and motor vibrations using a 3-axis accelerometer sensor. The MCU reads the real-time accelerometer data periodically and runs the algorithm to identify the motor health/status.

  • RE MCU will operate in 2 different power modes to minimize the current consumption.
  • High-performance clock (32MHz) speed is used to process the accelerometer data to identify motor health.
  • RE MCU stays in minimum power standby mode with 0.5µA current consumption for most of the time since motor vibration data is collected periodically (1 to 4 hours)
  • After wakeup from standby mode, the motor health monitoring algorithm runs to read and analyze the accelerometer sensor data to detect faults (Ex: Dynamic eccentricity fault)
  • Algorithm will capture 2048 samples of accelerometer values in iteration.
  • Fourier Transform of the captured accelerometer values are calculated to identify the faults.
  • Industrial
  • Office automation
  • Smart home appliances
