Double-stator switched reluctance machines have higher torque density and lower vibration and acoustic noise level in comparison with conventional switched reluctance machines. Static characteristics of a 8/6 Double-stator switched reluctance machine have already calculated using finite element method. However, no measurement has been presented for the static torque of the machine. This paper p...

The use of lithography and electroplating to fabricate variable-reluctance, nearly planar, integrated minimotors with 6-mm-diameter rotors on silicon wafers is described. The motors consist of six electroplated Permalloy@ horseshoe-shaped cores that surround the rotor. Copper coils are formed around each core. The Permalloy and copper electroplating baths, electroplating seed layers, and throug...

Identification of poor performance is in an integral part of government policy. The suggested approach for the identification of such problems, advocated by the General Medical Council, is that of appraisal. However, traditionally, there has been a reluctance to deal with poor performers, as all doctors have made mistakes and are usually only too ready to forgive and be non-critical of colleagu...
