  • Device and method for detecting axial play
    Patent number: 6766686
    Abstract: The axial play of a gearbox shaft (3) that meshes with a gearbox output (7) is determined by measuring the translational travel of the rotationally driven gearbox shaft (3) between the axial end stops (A1; A2) thereof while simultaneously blocking the gearbox output (7). The end stops define the axial play of the gearbox shaft (3). The commutator-dependent ripple of the motor current (IM) pertaining to the commutator motor which drives the gearbox shaft (3) in a drive unit (1; 2) is evaluated as the representative variable for the translational travel.
    Type: Grant

  • Testing procedure and apparatus for manufacturing of electrical drives with low output RPM
    Patent number: 4596154
    Abstract: Method and apparatus for testing electrical drive mechanism. A dog plate engages each drive and the drive is energized to rotate a pulley coupled to the dog plate. A weight is attached to the pulley by means of a cable. A controller energizes the drive, measures the torque output, and the speed and current input to the drive.
