✦ Synopsis

The control behaviour of an electro-dynamic motor, also known as a moving coil motor, is superior to other motor types. This is also true for the linear version of this motor type. The classic solution to produce an x-y movement with a long-stroke is to apply a stack of at least two linear motors. A rising moving mass, combined with a limited mechanical stiffness, limits the bandwidth. An alternative is the planar motor, which generates x-and y-movements. This paper describes an electro-dynamic planar motor with moving coils, which levitates and propels itself over long x-and y-strokes under full control over six degrees of freedom (6-DOF).

Driving mechanisms basically deliver two fundamental motions, i.e., linear and curvilinear motions. A piezoelectric laminated circular arc can serve as a curvilinear arc stator to deliver curvilinear motion on a spherical surface. This study is to evaluate ultrasonic vibration characteristics and mi

This paper presents a novel approach based on an adaptive parameter estimation technique for the dynamic balancing of the armature in an automobile starting motor. The proposed scheme is implemented on an experimental system comprising an unbalance measurement machine and a milling machine. Applying

In the study of dynamical systems the conditions for a critical point to be a centre are often sought. The sufficiency of such conditions is probed using various techniques; here we exploit the possible symmetry of a given system. We describe an application of GrΓΆbner bases in the search for a bilin
