  • Positioning drive and method for positioning an output element
    Patent number: 10700623
    Abstract: A positioning drive has a first stepper drive unit having a first stepper drive controller and a first stepper motor, and a second stepper drive unit having a second stepper drive controller and a second stepper drive. The two stepper drives and the power take-off element are force-coupled and drive-coupled by a mechanical coupling unit. A central unit controls the two stepper drive controllers by a control signal, in each instance. The control signals predetermine the stator reference field angle and the rotor reference field angle set by the stepper drive controller. The central unit has an overriding regulator for the position of the power take-off element, and a subordinate regulator for setting a tensioning moment for each stepper motor. The tensioning moments occur by setting a load actual angle at the stepper drive.
