Servo Drives Applications

Industrial servo drives applications are numerous: CNC machining, conveyor, robotics, etc. They can range from fraction of Watts applications to multi-kW applications and use induction motors (IM), permanent magnet synchronous motors (PMSM) and brushless DC (BLDC) motors for torque, speed or position control applications. The common caracteristic of those applications is their need to have high performance in transient mode to get smooth motor transition from one state to another.

MOTOR CONTROL ALGORITHM

  • Classical vector control (aka field-oriented control or FOC) with space vector PWM (SVPWM).
  • 2/3 stator phase current measurements
  • Measured rotor position and motor estimated speed based on rotor position.
  • Proportional-Integral (PI) flux and torque controllers.
