20080315709 | WIND POWER GENERATION SYSTEM, ARRANGEMENT OF PERMANENT MAGNETS, AND ELECTRICAL POWER-MECHANICAL FORCE CONVERTER - A wind power generation system | 12-25-2008 |
20090096314 | ELECTRIC MOTOR - The present invention relates to a new process for the preparation of NO-donating compounds using a sulfonated intermediate. The invention relates to new intermediates prepared therein suitable for large scale manufacturing of NO-donating compounds. The invention further relates to the use of the new intermediates for the manufacturing of pharmaceutically active NO-donating compounds. The invention further relates to a substantially crystalline form of NO-donating NSAIDs, especially 2-[2-(nitrooxy)ethoxy]ethyl {2-[(2,6-dichlorophenyl)amino]phenyl}acetate, the preparation thereof and to pharmaceutical formulations containing said crystalline form and to the use of said crystalline form in the preparation of a medicament. | 04-16-2009 |
20120112596 | DC COMMUTATOR DOUBLY SALIENT RELUCTANCE MOTOR - A dc commutator doubly salient reluctance motor is composed of a stator component, a rotor component, a commutator component, a brush component and a motor housing. The commutator does not rotate with a shaft, but the brush rotates with the shaft. The number of commutator segments connected with stator windings is the lease common multiple of the number of stator salient poles and the number of rotor salient poles. The number of brushes is at most equal to the number of the rotor salient poles. The connecting sequence that the commutator segments are connected with the stator windings is contrary to the distributing sequence that the stator windings are arranged on the stator salient poles. The speed-adjusting, braking and reversal of the motor are achieved by shifting the circumferential position that the commutator surrounds the shaft. The output power and the mechanical-electrical efficiency of the motor are changed by the included angles between the brush's front and back edges. Therefore, the special vibration and noise of switched reluctance motor are greatly eliminated. | 05-10-2012 |
20120326553 | ELECTROMAGNETIC VARIABLE-SPEED MOTOR TECHNICAL FIELD - An electromagnetic variable-speed motor includes a rotor having a plurality of permanent magnet structures, a stator disposed on the same axis as the rotor and having a plurality of teeth and a plurality of slots, and a variable-speed module disposed on the same axis as the rotor and the stator and at a position between the rotor and stator. Therein, the pole number of the variable-speed module no greater than the number of the slots such that the variable-speed module can be completely integrated with the stator, thereby providing a simplified yet strengthened structure which requires less components and fabrication costs than the prior art. | 12-27-2012 |
20130162096 | ELECTRIC ROTATING MACHINE - A tooth portion of a stator is divided into first and second tooth portions and in a relatively movable manner between a first position in which a magnetic resistance between the tooth portions is small and a second position in which the magnetic resistance is relatively larger than in the first position. When the second tooth portion is in the first position, the following equation is satisfied: (total magnetic resistance of main magnetic circuit C | 06-27-2013 |
20130207504 | STATOR MODULE AND MOTOR INCLUDING THE SAME - A stator module and a motor including the stator module are provided. The motor includes a stator and a stator module. The rotor includes a rotor core and a plurality of rotor poles arranged around a circumference of the rotor core, each generating a magnetic flux. The stator module includes a first stator and a second stator disposed coaxially with each other, each being rotatable in a circumferential direction and each having a coil wound thereon, and a rotation driving unit which controls a rotation of the first stator and the second stator through the same angle in opposite directions, thereby controlling a flux linkage of a rotor according to the rotational angle of each of the first stator and the second stator. | 08-15-2013 |
