Home Appliances Motor Drive Apps

Home appliances applications refers to washing machines, refrigerators, dishwashers and air conditionning units. As consumer products, they need to be extremely energy efficient and low cost. Typical motor power in those applications is in the range of 500W.

MOTOR CONTROL ALGORITHM

  • Sensorless vector control (aka field-oriented control or FOC) with optimized space vector PWM (SVPWM).
  • Advanced motor model & loss minimization algorithm (id  0) for maximum energy efficiency.
  • 1 shunt current measurement.
  • Estimated rotor position and motor estimated speed based on voltage and currents in stator synchronous frame.
  • Proportional-Integral (PI) flux and torque controllers.
  • Field weakening algorithm for high speed operation.
