This is the American Society for Engineering Education (ASEE) Engineering Case Library (ECL). The cases are accounts of real engineering work written for use in engineering education.The Engineering Case Program originated at Stanford University in 1964 with the support of the National Science Foundation. The library has been maintained by Rose-Hulman Institute of Technology and Carleton University. It continues under the sponsorship of the Design in Engineering Education Division (DEED) of the...

This article is from Sensors (Basel, Switzerland) , volume 14 . Abstract Powder metallurgy allows designers of electric motors to implement new magnetic circuit structures. A relatively new concept is the use of a magnet system consisting of various types of magnets on one rotor, for example sintered and bonded magnets. This concept has been applied to the design and manufacture of the four-pole rotor of a synchronous motor with 400 W power and a rotational speed of 1500 rpm. In this motor, the...

A model predictive control (MPC) scheme for a permanent-magnet synchronous motor (PMSM) is presented. The torque controller optimizes a quadratic cost consisting of control error and machine losses repeatedly, accounting the voltage and current limitations. The scheme extensively relies on optimization, to meet the runtime limitation, a suboptimal algorithm based on differential flatness, continuous parameterization and linear programming is introduced. The multivariable controller exploits...

In this paper the magnetic flux density distribution of a Halbach permanent magnet array for magnetically levitated planar motor is modelled analytically. The analytical first order harmonic model is derived initially from Fourier harmonic waves of magnetic field. Then the real magnetic field of a Halbach permanent magnet array is measured on a Teslameter‐centred measurement platform and the measured results are analysed. Next, the key parameter of analytical model is fitted and the...

A new controller is designed for speed and torque control of a Permanent Magnet DC motor based on measurements of speed and current. This research work focuses on investigating the effects of control of the speed and torque of two brushless dc motors that are mechanically coupled. Two controller design methods: the Root Locus method and Bode Plot method as well as two controllers: Proportional-Integral-Derivative (PID) and Proportional- Integral (PI) are used to obtain the control objectives of...

The supernova remnants G327.1-1.1 and G327.40.4 (Kes 27) are located 1.5 deg apart in the constellation Norma. In 1980, Einstein IPC observations discovered that both were irregular filled-center X-ray sources with possible point sources superposed. This paper describes new ROSAT position sensitive proportional counter (PSPC) observations which both map the diffuse structure and clearly show several unresolved sources in each field. Both remnants have bright emitting regions inside the limb...
