The thrust stopper is fixed to the base plate by means of screws. Stepper Motor Drive System. An additional object of the present invention is to provide a spindle motor with a structure that can prevent the rotating shaft and the rotor yoke from rising.
In contrast with externally driven motor spindles, we offer a high degree of compactness, precision and productivity. Because the housing supporting the bearing and the base plate are integrally formed in the present invention, assembly is made easier.
The rotor yoke is integrally formed with the turntable, and a felt is mounted on the top of the rotor yoke to place an optical disc thereon. Four bearings in our spindle motor.
Another object of the present invention is to provide a spindle motor having an improved structure that allows a simpler manufacturing process. Brushless motor having chucking mechanism, and disk driving device having the brushless motor. Search Search term s Search. The brushless motor has low noise and smooth operation, brushless motor without brush, less friction during operation. And the sensor technology for indexing and monitoring is built in.
Accordingly, the present invention is directed to a spindle motor that substantially obviates one or more problems due to limitations and disadvantages of the related art. For example, the built-in motor means fewer parts compared to a belt drive solution. The supporting mold is fixed between the core and the base plate at the same time that the thrust stopper is fixed to the base plate with screws. The rotor includes a rotor yoke, a magnet, and a rotating shaft.
Thus, an optical disc with music, images, etc. Find what you need to operate at peak productivity in our new online store! It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Therefore, the number of manufacturing processes increases due to the installing of the bearing housing. Information on further motor spindles for turning, grinding and milling can be found on the home page of our subsidiary company, Weiss Spindeltechnologie GmbH.
Turn off more accessible mode. The housing has the core disposed at an exterior thereof and has a bearing for rotatably supporting the rotating shaft provided within. Mechanically built-in-motor solutions are extremely compact and achieve maximum rigidity, a requirement for achieving maximum speeds and exact concentricity.
The washer is coupled in the fixing recess to prevent the rotating shaft from rising when it rotates. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. Motor for recording disk driving and recording disk driver using the motor for recording disk driving.
CNC Spindle Motor
Looking for motor spindles for use on milling machines and machining centers? The optical disc apparatus also includes a built-in actuator, which has a laser diode, a lens, a beam splitter, a photodetector, organic chemistry paula bruice solution manual pdf and other installed optical devices. Turn on more accessible mode. Tools Drive Technology Drive Technology.
Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. The base plate is integrally formed with a housing. The ledge prevents oil from leaking out from the housing when the rotating shaft rotates. Data erasure apparatus, data erasure method and method for writing servo patterns on recording disk. The stator has a bearing housing installed for holding a bearing in place.
An optical disc apparatus for reading optical discs has a built-in spindle motor that spins an optical disc at high speed. Disc drive spindle motor having a damper on a bottom surface of the spindle motor.
The present invention relates to a spindle motor. Weiss Spindeltechnologie GmbH To the top of the page.
The stator is disposed correspondingly to the rotor and includes a core and coils. Call us and we will do what we can to get it to you quickly. However, the bearing housing of a spindle motor according to the related art is a separate component, so that it must be installed following its manufacture.
Also, to prevent the rotating shaft and the rotor yoke from rising, a spindle motor according to the related art employs a washer assembled at its rotating shaft and bearing. To get a freight quote we will need to know the following Prefer to pick it up yourself? It is much more easy for users to care and maintennace the product.
CNC Spindle Motor
Spindle Motor And Inverter. Motor spindles Maximum performance in machine tools.
Will there be a dock or forklift. Further information Information on further motor spindles for turning, grinding and milling can be found on the home page of our subsidiary company, Weiss Spindeltechnologie GmbH.
The base includes a base plate for supporting the stator. Such optical discs have tracks formed to spiral outward from the middle, whereon digital data of a predetermined format is written. The supporting mold is disposed between the base plate and the core to support the core and adjust the height at which the core is assembled. Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Chucking device and brushless motor and disc driving device in which the chucking device is installed.
Brushless motor is brushless and low-interference. Motor having improved sleeve holder and base plate combining structure and optical disc drive using the same. High hardness, good elasticity, and not easy to deform. When the spindle motor operates, the rotor rotates at high speed. Provided is a spindle motor including a rotor, a stator, and a base.
