An efficient induction motor design for performance intensification using magnet software

Abstract

Summary In this research, a novel three‐phase 2.2 kW squirrel‐cage induction motor is designed in such way that the stator is constructed in a combination of magnets and coils and also the traditional aluminum rotor bar changed as copper rotor bar in the design. Therefore, the magnet should give additional repulsion for rotating the rotor hence reducing the input current. The simulation of novel designed induction motor is done by magnet software. Finite element approach gives accurate computations of the parameters demanded to acquire a world‐class prototype model, which is not feasible using mathematical tools. More than 80% of industries depend on this induction motor because it has a great effect in the industrial manufacturing and it is the integral part of the plant to develop the economic condition of developing countries. The average energy consumed by a motor is about 40‐80 times at initial cost. This article analyses the performance feature, which are efficiency, power factor, losses, energy, co‐energy, bar current, and bar current densities of novel designed induction motor using motor solver software. The designed induction motor using magnet software is imported to motor solver for the analysis. The performance of the analysis is compared with the conventional three‐phase 2.2 kW induction motor.

Energy Efficiency of Induction Motor Drives: State of the Art, Analysis and Recommendations

“…On the other hand, it is found that when the thickness of the laminations making up the stator package of a 0.37 kW three-phase induction motor is reduced, the efficiency increases by 1.4% and the power losses decrease [16]. In another study to improve the performance characteristics of a cage-rotor induction motor, an improved design was developed [17]. In it, a combination of magnets and coils is used for the stator, and the aluminum rotor is replaced by a copper one.…”

Rotor vibration unbalance compensation control of a bearingless induction motor

“…The advantages of simple structure, convenient maintenance, relatively cheap, and easy weak magnetic control provide a broad application perspective for the traditional induction motor. However, its service life and work efficiency are reduced by the problems of mechanical friction and heating 1‐4 . A bearingless induction motor(BL‐IM) has changed the support mode of the traditional motor rotor.…”

A harmonic vibration suppression approach in nonlinear induction motors

“…Electric motor driven systems convert nearly half of worldwide electric energy in mechanical energy 6 . Relevance on the design of high‐efficiency and robust operation strategies for the induction machine, with a significant reduction of energy consumption, can be thus inferred 7 . Variable frequency control drives for extra‐large induction motors play an important role for efficient use of the energy 8 .…”
