The frame includes a bottom face part, a stator fixing part which is formed to be bent from the bottom face part and which is fixed to the stator, and a shaft support part which is formed to be bent from the bottom face part so as to face the stator fixing part and which supports the end part on the output side of the rotation shaft, and the urging member is fixed by welding to an output side face which is a face on an output side of the shaft support part. The urging member is preferably a flat spring. | 01-07-2010 |
| 20100026117 | Motor stator, motor and electric pump unit - There are provided a tubular stator core having a plurality of tooth portions which protrude radially inwards and slots which are defined between the respective tooth portions and coils which are disposed on circumferences of the tooth portions. An insulator is attached to the stator core from an axial direction thereof for isolating the coils from the stator core. A radius of curvature of a corner portion of the insulator around which the coil is wound decreases continuously as the tooth portion extends from a root portion to a distal portion thereof. | 02-04-2010 |
| 20100289360 | BRUSH UNIT FOR AN ELECTRIC MACHINE, SPRING AND SEAL ARRANGEMENT FOR THE SAME, AND METHOD FOR THE PRODUCTION THEREOF - A brush unit for an electric machine has a simple and low-cost but robust design, and can be assembled at low-cost using simple process steps comprises four ring-shaped board elements are stacked on each other, namely two outer circuit boards, each of which is electrically conductively connected to one or more brushes. Two guide boards made of electrically insulative material disposed therebetween, comprise a shape having protrusions and recesses for forming radial guides for the brushes and receptacles for springs acting on the brushes. The springs are spiral springs wound around a mandrel, the flat ends thereof protruding past the springs being rotationally fixedly guided in a guide groove of each receptacle and able to engage behind a stop. In order to assemble the brush unit, the circuit and guide boards are stacked on each other in the axial direction and riveted, then the brushes are inserted in the guides in the radial direction and the springs are placed in the receptacles. | 11-18-2010 |
| 20110001376 | BRUSHLESS ALTERNATOR - Provided is a brushless alternator for preventing water from penetrating further inside through a gap between a distal end portion of a spool and a concave portion of a bracket. According to the brushless alternator of the present invention, a rotor includes: a rotor main body; and a coil body ( | 01-06-2011 |
| 20110204734 | Motor Grounding Seal - A shaft seal assembly is disclosed having a stator including a main body and axial and radial projections therefrom. The rotor may be radially extended to encompass the axial and radial projections from said stator. A passageway formed between the radial projection of stator and rotor results in an axial passageway having its opening facing rearwardly from the rotor and away from the source of impinging coolant and/or contaminant. A concentric circumferential receptor groove in the stator facing the housing allows insertion of a conductive insert for transmission of electrostatic charge away from the shaft through the shaft seal assembly to the housing and ground. The receptor groove is opposite the axial passageway and provides for both a substantially lower contaminant environment and improved engagement with the conductive insert. | 08-25-2011 |
| 20110316375 | HIGH EFFICIENCY SALIENT POLE MACHINE AND METHOD OF FORMING THE SAME - A salient pole machine and method of forming the same comprising a rotating field assembly and at least one inter-pole cap connected to the rotating field assembly and/or at least end coil cap connected to the rotating field assembly. Each inter-pole cap preferably includes a top surface that has a curvature and/or at least one cavity. Each end coil cap may include at least one support. The salient pole machine may also include at least one fan assembly independent of the rotating field assembly. In a preferred embodiment, the salient pole machine includes at least one mounting plate, wherein each fan assembly is mounted on the mounting plate. The inter-pole caps and the end coil caps preferably comprise composites, polymers, alloys, ceramics, or naturally occurring materials. | 12-29-2011 |
| 20130162074 | SEALING RESIN COMPOSITION FOR HDD MOTOR AND HDD MOTOR FABRICATED BY USING THE SAME - There are provided a sealing resin composition for a hard disk drive (HDD) motor and a HDD motor fabricated by using the same. The sealing resin composition includes: 45 to 65 parts by weight of urethane methacrylate resin; 35 to 50 parts by weight of methacrylate resin; and 2 to 4 parts by weight of acrylic acid. A sealing resin composition having a new composition is used as a sealing material of a FPC adhering part of the HDD motor, whereby a haze phenomenon due to air leak and outgas at the FPC adhering part may be improved and reliability of a HDD motor may be enhanced due to a reduction in generation of the outgas of the adhering part. | 06-27-2013 |
