The drive device (4) includes a drive plate (40), a ring-shaped permanent magnet (41) which is fastened to the underside of the drive plate, and six solenoids (43) arranged in a ring form underneath the permanent magnet, so that they lie opposite the permanent magnet and are connected in three phases and with eight poles. The drive device (4) includes a drive plate (40), a ring-shaped permanent magnet (41) which is fastened to the underside of the drive plate, and an amount of solenoids (43) which are positioned underneath the permanent magnet to produce a magnetic field interacting with the permanent magnet, when the solenoids are activated. A turntable (45) revolves synchronized with the drive plate, whereby a record can be arranged on the turntable, so that a cartridge with a receiver reads music from the record. Six solenoids are arranged in a ring form, so that they lie opposite the permanent magnet and are connected in three phases and with eight poles, so that the drive plate and the turntable revolve smoothly and solidly, and start quickly. |
