Magnetic bearing as Switched Reluctance Motor - feasibility study for bearingless Switched Reluctance Motor

2013 International Electric Machines & Drives Conference, 2013
This paper shows a general review of Switched Reluctance Motors (SRM), reports the conversion of Active Magnetic Bearing (AMB) to SRM and discusses methods to estimate the torque produced in SRM. AMB converted to SRM has been tested on a laboratory scale test rig and its torque production measured.

3D Magnetic Reluctivity Tensor of Soft Magnetic Composite Material

2006 12th Biennial IEEE Conference on Electromagnetic Field Computation, 2006
Soft magnetic composite (SMC) materials are particularly suitable for construction of electrical machines with complex structure and 3D magnetic flux. For design and analysis of such 3D flux machines, 3D magnetic properties of the magnetic materials should be properly determined, modeled and applied for calculating the magnetic field distribution ...

Comparison of Reluctance and Surface Permanent Magnet Coaxial Magnetic Gears

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020
The noncontact operation of magnetic gears offers significant potential advantages over mechanical gears. Reluctance magnetic gears (RMGs) have been proposed as an alternative to surface permanent magnet gears (SPMGs) at high speeds. This paper explains the operating principles of RMGs and provides a thorough parametric comparison between RMGs and ...

A permanent magnet‐assisted synchronous reluctance motor

Electrical Engineering in Japan, 2003
AbstractPermanent magnet motors have attracted a lot of attention recently for their potential for saving energy. However, they are only used for certain applications because the magnets are expensive. This paper discusses the optimum design of the low‐cost, highly efficient magnet‐ assisted reluctance motors with a minimum amount of magnets. The motor

Reading of magnetic records by reluctance variation

Proceedings of the IEE - Part B: Radio and Electronic Engineering, 1956
The paper describes a method of reading information recorded on a magnetic medium, in which the velocity of the medium can have a wide range of values including zero. Read signals are obtained by varying the reluctance of the reading head. With a head constructed according to this principle 50 binary digits per inch have been read from magnetic tape.
