To share and divulge lessons learned using ESP system first application in a mature field operated by Petrofac Mexico, using cutting-edge technology and an Electric Submersible Pump (ESP) system with synchronous permanent magnet motor (PMM) ϩ Power Save pump in Santuario 132 well, operated by Petrofac Mexico at the service of Petroleos Mexicanos (Pemex), for 384 days.In this technical work the ALS selecting process is explained in detail, as well as new technology implementation in ESP systems with synchronous permanent magnet motor (PMM) ϩ Power Save pump with staged vortex type semi-compressors, in the Santuario 132 well, operated by Petrofac Mexico for Pemex, is presenting the recommendations and good practices carried out mainly in the phases : Conceptual (design, specifications and manufacturing), Installation (assembly and commissioning), Operation (operational reliability and optimization), Out of Operation / Fail (methodology for analyzing the fault); phase Removal (analysis and inspection system) and last phase learning (change in design or procedures).

The Toyota Prius MG2 electric motor and its upgrades, since its first appearance in 1997, are presented in this paper. This electric motor has an Interior Permanent Magnet (IPM) fitted with Rare Earth (RE) magnets, which presents clear advantages over the more widely used Induction Motors (IM). The principal advantage is its high power-density value that makes it a leader in the Electric Vehicles (EV) market. This technology, however, faces a problem, in so far as the global production of RE magnets is an exclusive monopoly of China, (motivating the United States and Japan, among others, to investigate alternative systems). In this paper, the proposal is to substitute the sintered magnet in current use by the bonded type of magnet. The use of bonded magnets permits curved geometric forms, reducing the use of dysprosium, one of the most controversial elements of sintered magnets. These materials are compared using Finite Element Analysis (FEA) in the design of various rotor models including the proposal of a model with bonded magnetic materials, with the advantages of curved magnets and a dual layer arrangement. The proposed rotor model yielded a considerably higher power density than the model developed by Toyota.
