| 20080246358 | Magnetic bearing spindle device for machine tool - The control device displaces the main shaft in the axial direction and in the radial direction within the range of the gap between the rib member of the main shaft and the axial magnetic bearing and the gap between the main shaft and the radial magnetic bearings, by controlling the attraction forces of the axial electromagnets and the radial electromagnets, whereby the main shaft can be positioned. By controlling the axial magnetic. bearing and the radial magnetic bearings, it becomes possible to freely displace only the main shaft in the axial direction and in the radial direction, and therefore, the main shaft can be positioned at high speed and with high precision. Moreover, there is no necessity of providing the feeding mechanism in which the ball screw mechanism and linear motor etc. are employed for the purpose of displacing the magnetic bearing spindle device, and hence, reduction of the production cost for the grinding apparatus can be achieved. | 10-09-2008 |
| 20080252161 | Magnetic bearing device and magnetic bearing spindle device - A control device includes a differential amplifying circuit for obtaining a difference between values of exciting currents (exciting voltage values) supplied to a pair of axial electromagnets and a pair of radial electromagnets, multiplying the obtained difference by coefficient times, and outputting it as the bearing load in an axial direction and a radial direction. The exciting current includes steady current supplied to the axial electromagnets and the radial electromagnets and control current which varies by the displacement of a main shaft. By supplying the steady current to the axial electromagnets and the radial electromagnets, the magnetic attraction force of the axial electromagnets and the radial electromagnets having non-linearity is linearly approximated. Accordingly, the difference between the values of the exciting currents (exciting voltages) supplied to a pair of electromagnets is obtained and is multiplied by coefficient times, thereby obtaining a value corresponding to the bearing load. | 10-16-2008 |
