Performance Assessment and Comparison of Two Types Linear Motors for Electromagnetic Catapult
نویسندگان
چکیده
Linear motors are strong candidates in electromagnetic launching technology for space-use. In this paper, two types linear motors, including parallel magnetic circuit linear permanent magnet brushless DC motor (PMC-LPMBDCM) and serial magnetic circuit linear permanent magnet brushless DC motor (SMC-LPMBDCM), have been presented for electromagnetic catapult. The rudimental configurations of these two-types linear motors are researched respectively. Then the contrast of performance between PMC-LPMBDCM and SMC-LPMBDCM is investigated detailedly. The electromagnetic properties and thrust characteristics are researched by finite element analysis (FEA) and experiment. Simulated and measured results can provide useful references to select the suitable type of motor for electromagnetic catapult.

Improvement of Electromagnetic Forces in a Single-Phase Induction Motor by Providing a New Winding Distribution
Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
