    - 1.1.1.1 Permanent Magnet Synchronous Motor
      The Permanent Magnet Synchronous Motor (PMSM) is the most preferred choice for motor control applications. Due to their permanent magnet rotor, they also have higher torque with smaller frame size and no rotor current, all of which are advantages over AC Induction Motors (AICMs). With their high power-to-size ratio, PMSMs can help make the design smaller without the loss of torque. These strengths enable the usage of PMSM in a broad range of variable frequency drives (VFDs) applications..
    - 1.1.1.2 Field Oriented Control
      The Field Oriented Control (FOC) is the conventional control scheme for permanent-magnet synchronous motors. It generally results in smoother torque, slightly higher efficiency, and higher torque-speed curve, compared to six-step control, but requires a measurement or estimate of rotor position, and is more computationally intensive.
