    Tips: Why is the bearing of 20 hp servo spindle motor overheating?

    • 20 hp servo spindle motor's own reasons:
    1. The inner and outer rings of the bearing are too tightly matched.
    2. There is a problem with the shape and position tolerance of the parts, such as the poor coaxiality of the machine base, end cover, shaft and other parts.
    3. Improper selection of bearings.
    4. The bearing is poorly lubricated or the bearing is not cleaned, and there is debris in the grease.
    5. Shaft current.
    • Improper use of 20 hp servo spindle motor:
    1. Improper installation of the unit. For example, the coaxiality of the AC servo spindle motor shaft and the dragged device shaft does not meet the requirements.
    2. Pulling the pulley is too tight.
    3. Improper maintenance of the bearing, insufficient lubricating grease or exceeding the service life, drying and deterioration.

    Great value and high quality!
    Does zero drift has to be restrained?

    ATO Responded
    In the process of closed-loop control, the presence of zero drift can have an effect on the control result, so it is preferable to suppress it. Use the parameters for suppressing zero drift on the controller or servo, and adjust them carefully so that the motor speed converges to zero. Since zero drift itself has a certain randomness, it is not necessary to require the motor speed to be absolutely zero.
