IGSPICE simulation of induction machines with saturable inductances
IEEE Transactions on Energy Conversion, 1989A novel approach to the dynamic analysis of induction machines with saturable inductances is presented. The machine dynamics are represented by a set of nonlinear time-varying differential equations. The machine parameters (i.e. saturable inductances) are modeled by closed-form nonlinear functions.

An improved estimation of the induction machine leakage inductances
IEEE Transactions on Industrial Electronics, 1999An alternative method for the determination of the induction machine leakage inductances is proposed. The stator transient inductance is the only parameter needed, besides the nameplate data. Results show the accuracy of the technique.

Induction Machines Efficiency Mapping
2020 19th International Conference on Mechatronics - Mechatronika (ME), 2020The paper presents a simple yet powerful method of efficiency mapping of induction machines. The whole calculation process is based on knowledge of induction machine equivalent circuit parameters and approximation of losses based on known dependencies on speed, current and magnetic flux linkage.

State Machines as Inductive Types
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2007We describe a way to write state machines inductively. The proposed method makes it possible to use the standard techniques for proving theorems on inductive types to verify that state machines satisfy invariant properties. A mutual exclusion protocol using a queue is used to exemplify the proposed method.

Machine induction of geospatial knowledge
1992Machine learning techniques such as tree induction have become accepted tools for developing generalisations of large data sets, typically for use with production rule systems in prediction and classification. The advent of computer based cartography and the field of geographic information systems (GIS) has seen a wealth of spatial data generated and ...

Efficiency tests of induction machines
Electrical Engineering, 1934Several different types of tests For the efficiency of induction machines are discussed in this paper, and results obtained by the different methods are compared. The procedure involved in making the different types of tests is given in detail. In the determination of losses, special attention is given to the stray load loss, which, in most previous ...

Nowadays, the induction machine is by far the most commonly used electrical machine in electrical drives (for applications that require a highly dynamic behaviour or where energy efficiency or compactness is primordial the permanent magnet synchronous motor may be preferred, however).

Power Losses in Induction Machines
Transactions of the American Institute of Electrical Engineers, 1934Losses in induction machines have been subjected to a detailed study by many investigators, but due to the complex nature of some of these losses, particularly several forms of load loss in induction motors, a clear understanding of their nature, has not been available.

Machine design software for induction machines
2008 18th International Conference on Electrical Machines, 2008This paper introduces a software tool for the design of cage-rotor induction machines. The software covers electromagnetic dimensioning, thermal calculations and cooler design as well as mechanical calculations of critical speeds and natural stator frequencies.
