This is accompanied by a drop in torque as soon as the speed exceeds the nominal value. Due to high power density, high efficiency, and accurate control performance, permanent magnet synchronous motors (pmsms) have been widely adopted in equipment manufacturing and energy transformation fields To expand the speed range under finite. A pmsm (permanent magnet synchronous motor) has high efficiency and torque characteristics compared to other motors To maximize the potential of a pmsm, several control methods can be used Field oriented control (foc) is one of the control.
In case of the pmsm, the rotor field speed must be equal to the stator (armature) field speed (i.e., synchronous) The loss of synchronization between the rotor and stator fields causes the motor to halt.
