Latest Patents

Zhengmeng Liu holds a patent for a "Double stator permanent magnet linear motor and design method for increasing magnetic field modulation." This invention discloses a double-stator linear vernier permanent magnet (DS-LVPM) motor and a method to enhance the magnetic field modulation effect. The motor features a primary component and first and second secondaries on both sides, separated by an air gap. The secondary includes modulation teeth, and the primary is bilaterally symmetrical with permanent magnets embedded in the yoke of the primary core elements. This design addresses the issue of flux leakage at the ends of permanent magnets in conventional VPM motors, improving the utilization of permanent magnets and increasing the thrust density of the motors. Additionally, the motor secondaries are laminated with silicon steel sheets, which conserves permanent magnet material and significantly reduces costs for linear long-stroke applications. By adjusting the permanent magnet structure parameters, the design utilizes finite element methods (FEM) to iteratively calculate the parameters that correspond to maximum electromotive force (EMF).
