This paper presents the design and control of a magnetically suspended ceiling actuator which combines four iron-cored linear actuators and a checkerboard permanent magnet array for an infinite planar stroke. When the actuators are rotated with respect to the PM array, it is shown that the thrust and normal force produced by the three-phase linear actuators can be controlled by applying Park's transformation. The design of the iron-cored linear actuators is optimized for minimum losses when the translator inside the ceiling actuator and a payload are accelerated in the xy-plane. The optimization is performed using an analytical model is. Simulations of the optimized design with a 3D FE-model, show a maximum tracking error of 1 μm and rotations of 30 μrad when the translator is moved and controlled in 6 DOF.

Permanent Magnet Generator

This paper discusses and analysis the constant voltage of vehicle applied permanent magnet generator. The permanent magnet can produce magnetic field in an air gap with no excitation winding and no dissipation of electric power, when the rotor turns, the magnet field turns, the generator generates electricity, with the permanent magnet material of high remnant magnetic induction and the optimized design of the generator, the output voltage is improved when the engine at low speed. We develop a single-phase double half-wave electric regulator is to ensure the stability of the output voltage and can direct output direct current.

Determining Factors

Wind power is an important source of green power. The equipment, generators, and power systems are all determining factors of equipment efficiency. High efficiency generators of medium and small size are widely used in daily life. Cogging torque is a major issue affecting generator efficiency. This paper proposes an optimized design for permanent-magnet synchronous generators using arc-shaped magnets to reduce cogging torque. The proposed approach improves performance significantly.
