Design and Simulation of a Moving-magnet-type Linear Synchronous Motor for Electromagnetic Launch System

The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...

Eddy Field Measurement by Using Search Coils for Bending Magnet

In order to estimate a field disturbance of a guiding field of a synchrotron due to an eddy current, magnetic fields in a bending magnet have been measured. The magnet was excited by a sinusoidal current with a repetition of 30 Hz. Two search coils were used in the measurements. One is a reference coil and the other is a measurement coil. An imaginary part of an eddy field was derived from phas...

Magnetic Force Calculation between Circu- Lar Coils of Rectangular Cross Section with Parallel Axes for Superconducting Magnet

The electromagnetic force between two misaligned coils (coils with parallel axes) with uniform current density distribution and rectangular cross section based on the derived semi-analytical expressions was presented. Using the semi-analytical expressions for magnetic force between filamentary misalignment circular coils we calculate the propulsive and the transverse magnetic force. In order to...

Study on interior permanent magnet synchronous motors for hybrid electric vehicle traction drive application considering permanent magnet type and temperature

Recently, interior permanent magnet synchronous motors (Interior-PMSMs) have become known as a good candidate for hybrid electric vehicle (HEV) traction drive application due to their unique merits. However, the dynamic and steady-state behaviors of these motors are quite dependent on the permanent magnet (PM) type, configuration, and volume in rotor structures. This paper uses a novel structur...
