The electric motor is the mechanism that transforms electrical energy into mechanical energy. Nowadays, electric motors are the cause of a considerable share of the use of electricity and therefore of the energy consumptions (70% in the industrial sector and 25-30% in the tertiary sector). Faced with ever-increasing energy demand and with a view to adhering to the all-over-the world imperative of adopting measures to reduce energy consumption in all the involved sectors, the use of efficiency enhanced electric motors is required. Generally, the efficiency of an electric motor depends on the type of motor, the size of the motor, the utilization factor, but also on the quality and quantity of the materials employed. Therefore, from all these aspects the need of using energy and costefficient components for developing electric motors arises. This review paper aims to draw a general framework on the methods of increasing efficiency and of reducing weight of the electric motors.

“…In this situation, the permanent magnets have a temperature of roughly 50.0°C. 28 The heat transfer rate and airflow inside the motor are very much important in motors that use the air-cooling technique. The process of heat transfer for a little space is influenced by internal airflow.…”

The paper gives a comprehensive review of lightweight materials/design of permanent-magnet-synchronous-motors and different temperature-reducing (cooling) techniques. The paper discusses and compares various simulations and performance analyses of different practically implemented solutions. Temperature and performance analyses for cooling systems using phase-changing materials, cooling jackets, and other coolants are investigated, and the use of lightweight materials and composites is compared. A discussion on numerical methods and results (finite element method analysis), in order to get a more-precise thermal mapping model for different machine structures is presented. Finally, the best temperature-reducing-cooling systems methods along with the good lightweight designs which increase the overall efficiency of the motor are discussed and commented on.

This paper gives a brief review of advanced cooling methods and applications to the permanent magnet synchronous motors (PMSMs), as well as investigates the cooling systems design problem for PMSM systems. Heat sources and losses together with analytical and practical analyses are described. Next, the temperature distribution and its influence on the PMSM is investigated using simulation results. The main part of the paper includes a review of the proposed cooling methods that will release the requirement of heat transfer of the PMSM. The finite element methods (FEM) are applied using the AnSys CFD software to obtain high accuracy thermal model of the PMSM system. The new developed forced air-cooling methods are given in details, which enable to effectively redistribute the temperature and heat transfer increasing the efficiency of the PMSM machine. Examples of CFD simulation are outlined to illustrate the effectiveness and benefits of the strategies developed.
