Improvement of Thrust Ripple in PMLSMs Considering Magnetic Saturation Using the Frozen Permeability Method

Key Points

• Thrust ripple was significantly reduced, enhancing overall motor performance.
• A peak thrust ripple reduction of up to 30% was achieved in controlled tests.
• This analysis employs the frozen permeability method to assess magnetic saturation effects.
• Improved model accuracy may lead to better designs in permanent magnet motors.
