Analysis of Electromagnetic Characteristics of a Novel Toroidal Acceleration Linear Motor
文献摘要：
A high thrust density linear motor, which adopts a novel toroidal structure, applying to load acceleration in confined space is proposed. The basic structure of the toroidal acceleration permanent magnet synchronous linear motor (TA-PMLSM) is depicted, both with its parameters listed. The main characteristics such as air gap magnetic density and electromagnetic thrust are discussed by establishing the electromagnetic field equation in the cylindrical coordinate system. And simulation comparison between the Halbach permanent magnet array and the classical radial one is also made to get a higher density of the magnetic and electromagnetic thrust. Compared with the conventional radial permanent magnet array, results show that the amplitude of back EMF of ring motor under the action of Halbach permanent magnet array has a better sinusoidal, the magnetic density of the air gap increases by 1.3 times, the thrust density increases by 1.42 times, and the main harmonic content of the two referred physical quantity decreases significantly.
