...Feng Dong; Hao Chen; Shuai Xu; Sihang Cui Purpose This paper aims to present a novel position sensorless control scheme with fault-tolerance ability for switched reluctance motor at low speed. Design/methodology/approach First, the detection pulses are injected in the freewheeling and idle...

... by implementing methods for reducing the number of failing AFMs. For example, improving the motor assembly precision leads to reduction of the machine parameters deterioration. Findings Assembly tolerances on electric motor characteristics should be investigated during motor design. The presented measurements...

... to investigate non‐ideal manufacturing and in particular its influence on the cogging torque. The two considered tolerances of non‐ideal manufacturing, which influence the cogging torque and which are known as crucial, are magnetisation faults and a static eccentricity of the rotor (Herranz Gracia, 2008...

...Jens Haueisen; Hartmut Brauer; Rumena Stancheva; Ilona Iatcheva; Angel Angelov Purpose The purpose of this paper is to introduce a method for evaluating the production tolerances influence on the practically realized optimal solution of electrotechnical devices. The influence is estimated...

... is used for finite element‐based performance calculations of the prototype electromagnetic devices. The intention of this paper is to propose an optimization algorithm which attempts to embed the “tolerance” (Zhang and Wang, 1998) constraint within its processes by trying to avoid detailed local...

...G. Spagnuolo Purpose To introduce an interval arithmetic (IA)‐based approach to tolerance analysis and design and to yield evaluation. The technique distinguishes itself by its reliability in the detection of even non convex and/or non simply connected regions of acceptability. Design...
