20090009010 | Low-Noise, High-Speed, High Precision and High-Thrust Flux Reversal Motor for Linear or Rotary Motion System - Disclosed herein is to a flux reversal motor. The flux reversal motor includes a mover, and a plurality of permanent magnets. The mover moves linearly relative to a stator. A plurality of permanent magnets, having identical polarities, is provided in the end of each mover tooth. The permanent magnets are arranged on the left and right sides of a protrusion of the end of the mover tooth. Thus low noise/low vibration, high speeds, high precision, and high thrust motion can be realized. | 01-08-2009 |
20100259112 | STRUCTURE FOR LINEAR AND ROTARY ELECTRIC MACHINES - Disclosed herein is a structure for linear and rotary electric machines. The present invention provides a modular mover structure which includes coils that have an electrical phase difference of 180°, so that the path of magnetic flux is shortened, thus reducing the size of the machine and mitigating the back-EMF unbalance. Furthermore, the modular mover structure can be modified into various shapes. For example, when a skew structure is applied to a mover or stator iron core, the force ripples in an electric machine can be reduced. In addition, when a hinge structure is applied to a modular mover iron core, the mover can move in a linear and curved manner. Moreover, the structure of the present invention can be applied to a rotary electric machine. In this case, because the number of poles can be easily increased, a low speed high torque direct drive type rotary electric machine can be realized. | 10-14-2010 |
