This paper presents an analytical formula for the permanent magnet (PM) magnetomotive force (MMF) in a slotted PM rotating motor. To derive this formula, an analytical 2D solution of Poisson's equation for the equivalent slotless configuration using the Fo ...

This paper describes a linear motor optimization based on an analytical model. The studied motor, also called "ironless", consists of an iron core U shape with permanent magnets on each side, between which the coils can move. The glider which supports the ...

In order to develop the new generation of motor pump (water) for heating or for cooling applications, a structural motor study was made to determine the best motor corresponding to the specifications. Stator structures, winding, supplying mode, pole number ...
We present an exact model for determining the cogging torque in a brushless DC (BLDC) motor. It is based on the conformal mapping (CM) method, by which the motor configuration is transformed to a configuration where the magnetic field can be determined. Th ...
This paper presents technology aspects and choices relative to worldwide MAGLEV projects such as the German Transrapid, the Japanese MLX, the USA Inductrack and the Swissmetro. Propulsion, magnetic levitation and guidance, transfer of energy to the vehicle ...
We present an application of the conformal mapping (CM) method to determine the magnetic field and force in an electromechanical actuator. First, we show how to find, using a special type of CM known as the Schwarz-Christoffel mapping, the magnetic field i ...
A theoretical analysis of temperature distribution on an artificial ventricular assist device is performed using three-dimensional finite element modelling. The model consists of 6000 solid elements representing all the ventricle components. In order to fi ...
To be able to calculate the performances of a hybrid stepping motor or to design it in a short time, it is essential to apply an efficient model, accepting a slight loss of precision. Using software based on finite elements and executing calculations are d ...
This paper presents a solution to design a linear reluctant transducer characterized by a quasi-linear force versus the displacement and to simplify the electronic supply as well as the control. The model, the verification by a finite element simulation an ...
The paper presents a new type of electronically-switched doubly-salient permanent-magnet (DSPM) small motor for household appliances. Its basic structure is similar to that of a switched reluctance motor, except for the presence of high-energy PMs inside t ...
