To more efficiently design high performance vehicular permanent magnet motor, an electromagnetic-thermal integration design method is presented, which considers both the electromagnetic properties and the temperature rise of motor winding when determining the main dimensional parameters of the motor. Then a 48-slot and 8-pole vehicular permanent magnet motor is designed with this method. The thermomagnetic coupling design is simulated and validated on the basis of multiphysical domain on finite element analysis. Then the prototype is analyzed and tested on a newly built motor experiment platform. It is shown that the simulation results and experimental results are consistent, which validate the accuracy and effectiveness of the new design method. Also this method is proved to well improve the efficiency of permanent magnet motor design.

Abstract The most frequently performed bariatric surgery is the laparoscopic Roux-en-Y gastric bypass (LRYGB). An uncommon complication of LRYGB is gastro-gastric fistula (GGF). Possible causes of GGF include incomplete transection of the stomach during the initial surgery, staple-line leaks in the post-operative period and marginal ulcers. The optimal management of GGF is still under debate, with medical, endoscopic and surgical treatment modalities available. The authors present two cases of a GGF successfully managed with a laparoscopic surgical approach, after failed medical and endoscopic treatment.
