Design of efficient, cost effective three phase induction motors for ceiling fans in India
… them are driven by inefficient, low cost single phase induction motors, the total power loss is nontrivial. To overcome the inefficiency of single phase induction motors, brushless dc motors have been increasingly used in ceiling fans to achieve high efficiency and power factor at multiple speed …

The analysis of airgap eccentricity in three-phase induction motors using finite elements for a reliable condition monitoring strategy.
… investigation into airgap eccentricity in three phase induction motors. Airgap eccentricity is an inherent condition in induction motors which if left undetected can result in motor failure. It is therefore of interest to detect and quantify the level of airgap eccentricity. A literature …

Computational aspects of on-line machine monitoring.
The detection of the fault phenomena found on three phase induction motors, as widely used in industry, from an electrical engineering viewpoint has been investigated. Various transducers are used, on a real motor, to establish connections between known fault and measurable changes in the signals …

Three-Phase Generation Using Reactive Networks
<p>Household appliances utilize single-phase motors to perform everyday jobs whether it is to run a fan in an air conditioner or the compressor in a refrigerator. With the movement of the world going “green” and trying to make everything more efficient, it is a logical step to start with the items …

Composite load modeling for power systems: Model reduction, identification, and application to conservation voltage reduction
… load model with the combination of static load, three different classes of equivalent three-phase induction motors, single-phase A/C motor, electronic load and an aggregated DER has been proposed by the Western Electricity Coordinating Council (WECC). However, the high model order and the large …

Non-intrusive efficiency estimation of inverter-fed induction machines
Motorised loads using induction machines use approximately 60% of the electricity globally. Most of these systems use three-phase induction motors due to their robustness and lower cost. They are often installed in continuously operating industrial plants/applications that require no operational …
