Abstract
Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...
