Comparison of AC Motors to an Ideal Machine Part II—Non-Sinusoidal AC Machines
IEEE Transactions on Industry Applications, 2019This two-part article compares the torque performance of 12 types of ac machines based on the same surface current density, tooth flux density, and rotor dimensions. Part II examines the torque capability of machines more recently developed which utilize the wave shaping capability of a solid-state frequency inverter.

Electrical drives are used to convert electrical energy to mechanical energy. They all use a magnetic field as the medium for energy conversion. As we will see the conversion is reversible, just as it is with hydraulic drive systems.

New capacitive synchronous AC machine
2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015The paper proposes a new type of the synchronous AC machine operated on a principle of the electric field effect. The proposed machine has smaller size and lighter weight than the standard electromagnetic synchronous machines with the same rated parameters.

Dynamical Models of AC Machines
2015This chapter presents a detailed review of the basic concepts describing the mechanical and electrical behavior of alternative current (AC) machines, which will be used extensively in the following chapters. AC machines, specifically the permanent magnet synchronous motor (PMSM) and the induction motor (IM), will be studied.

Preliminary study on AC superconducting machines
IEEE Transactions on Magnetics, 1988Issues involved in developing AC superconducting machines are reviewed with respect to the development of a superconducting coil and the overcurrent protection system of a superconducting transformer. A 4-kVA superconducting coil using 100-A-class 50/60-Hz superconductors was made and tested.

Practical Control of AC Machine
2020The electric machine based on a control system with the machine model is not a simple task but requires necessary simulation tools to understand its basic operation. The complexity of their models suggests performing first simulations both in open and closed loop, without using an electric drive (VSI or DC servo stage).

Fault detection in large AC machines
ICM 2001 Proceedings. The 13th International Conference on Microelectronics., 2001The emerging techniques of artificial neural networks (ANNs) are applied to the problem of developing an artificial neural system capable of detecting interlayer faults in large AC machines using line-end coil voltage measurements. The proposed ANN system is a two-layer back propagation neural network, which is basically a classifier capable of ...

AC electrical machines can act as generators to convert mechanical energy into electrical energy or motors to convert electrical energy into mechanical energy. This chapter discusses synchronous machines, and induction machines. Example problems with solutions as well as actual problems in AC machines were also provided in the end of this chapter.

The commutator in a DC machine performs a complex function which we have not attempted to analyse in detail; the performance equations, on the other hand, are relatively simple. With the AC synchronous and induction machines, the situation is reversed. The absence of a commutator simplifies both the structure and the detailed analysis, but the machine ...
