Design Consideration of Back-EMF Constant for 3-D.O.F. Spherical PM Motor

Optimal Design of Ultra-High Speed Axial Flux Permanent Magnet Motor with Sinusoidal Back-EMF

An Approach to Basic Design of the PM-type Spherical Motor

-Authors propose the spherical electromagnetic actuator that applied Surface Motor. The feature of this actuator is the ability to arrange the magnetic poles uniformly by distributing the stator's magnetic poles in triangular lattice. In this paper, we report that the fundamental structure of this actuator and secondary side permanent magnets arrangement, and we measure the thrust force charact...

Dynamic modeling and design optimization of a 3-DOF spherical parallel manipulator

This paper deals with the dynamic modeling and design optimization of a three Degree-of-Freedom spherical parallel manipulator. Using the method of Lagrange multipliers, the equation of motion is derived by considering its motion characteristics, namely, all the components rotating about the center of rotation. Using the derived dynamic model, a multiobjective optimization problem is formulated...

CONSIDERATION OF DESIGN FOR PRODUCTION PRINCIPLES IN SHIP HULL DESIGN

In designing for ship production, the production method should be considered and it’s possible to reduce the manufacturing cost in designing procedure. A review of background of ship design that had minimized production costs, shows the principles and problems of these methods. Modern designing methods for manufacturing, considers hydrodynamic efficiency and less manufacturing cost. Quant...

Static Balancing of Spherical 3-DOF Parallel Mechanisms and Manipulators

The static balancing of spherical three-degree-of-freedom (DoF) parallel mechanisms and manipulators is addressed in this paper. Static balancing is defined here as the set of conditions on mechanism dimensional and inertial parameters which, when satisfied, ensure that the weight of the links does not produce any torque (or force) at the actuators for any configuration of the mechanism, under ...
