The paper deals with two types of optimisation problem: optimised source distribution and the shape optimum design, using continuum design sensitivity analysis (CDSA) in combination with standard electromagnetic (EM) software. Fast convergence and compatibility with existing EM software are the distinctive features of the proposed implementation. To verify the advantages and also to facilitate ...

The initial results of a research aimed at investigating to what extent high resolution encoders, which are getting available for common industrial motion control and robotics applications, can be exploited to compensate for non linear friction terms are presented in this paper. The 22 bits resolution sensor used allowed a neat analysis of the dynamic behavior of friction forces in the preslidi...

Aiming at the optimization of cogging torque 12 pole 36 slot embedded permanent magnet motor, analyzing generation principle torque, putting forward design auxiliary based on Taguchi method, using Maxwell finite element simulation tool, and selecting optimized data, through orthogonal experiment data processing, finding final scheme slot. The results show that, method can effectively suppress u...

<span lang="EN-US">This paper analyzes the feasibility of converting brushed direct current (BDC) to brushless (BLDC) motor by substituting wound rotor with a permanent magnet. The aim is overcome low quality rewinding rotors. conversion was performed redesigning motor, referring old stator dimensions and specifications. Some suitable speed control systems were also examined. Technical an...

Cogging torque is a critical dilemma in Permanent Magnet Brushless DC (PMBLDC) motors. In medium-low power PMBLDC motors, redundant vibrations and forbidding noises arise as result of the harmonic magnetic forces created by cogging torque. This paper introduces simple approach for minimizing motors applying placement irregularities rotor magnets. An angle shift magnets surface-mounted helps to ...

Performance evaluation of an axial flux surface mounted permanent magnet (PM) field controlled TORUS type (FCT) disc machine is presented in this paper. This new machine is an axial flux configuration with true field weakening capability since the flux is controlled by the DC field winding rather than opposing the magnets. Structure and operating principles are summarized in the first section. ...
