MOTION CONTROLLER DEVICE FOR MAGNETIC TAPE AS WELL AS MOTOR CLEANING DEVICE AND METHOD

摘要

PURPOSE: An enhanced method for cleaning a commutator-brush interface in a direct current motor is provided which the motor is installed in a unit driven by or operated in the unit and cleans a commutator-brush interface in a direct current controlled speed motor useful in a tape drive of a data processing system and is capable of being controlled and provides information showing the results of the cleaning process. CONSTITUTION: A motor cleaning system(101) includes the power supply(103) and a control unit 105. The power supply(103) directs its current to the control unit(105) where it is distributed to the motors(16,21) via the output lines(32,33), respectively. The control unit 105 is activated by a signal called the clean motor signal along the line(107). The clean motor signal was emitted by a recording channel control unit(35) or any other control unit. The method and apparatus for cleaning the motors delivers the maximum amount of current to the brush-commutators interface in the shortest time. A method cleans the motors used while the tape drive cartridge has been unloaded from the tape drive and the drive is idle.
