Product Description:

The ADF134C-B05TC3-BS00-C2V1 belongs to the ADF Main Spindle Motors series from Bosch Rexroth Indramat. It is a liquid-cooled asynchronous spindle unit designed to deliver continuous, high-torque rotation for machine tools and other automated production centers that rely on precise speed regulation under heavy loading. The motor integrates directly with flange-mounted machine frames, providing compact, thermally controlled power for automated machining, drilling, and milling tasks. Its operating role is suited to spindle applications in which cutting resistance changes quickly and the drive must maintain stable rotation through those load variations.

This model has a frame size of 134 and length code C, which indicate the active stator volume and the motor's continuous output range. Rotor balance is classified as R DIN ISO 2373, reducing vibration and allowing high spindle speeds without excessive bearing stress. Stable rotor balance is important in machining centers because vibration can affect tool engagement and surface finish. Internal heavy-duty bearings support the radial and axial loads that occur during aggressive cutting cycles. As a liquid-cooled asynchronous motor, heat is carried away by a closed coolant circuit, so the housing temperature remains stable during sustained high-current operation.

An axial port with a rapid-action coupling simplifies attachment of the external coolant hose. The motor is delivered without an encoder unit, so position feedback must be supplied by an external sensor or estimated by the drive. This arrangement allows the spindle system to use a separate measuring device when the application requires it. Installation uses flange mounting, and incoming power is routed through a top-mounted junction box that faces side A of the shaft. A plain shaft with a fitted seal ring helps prevent coolant ingress near the machine interface. The motor has no holding brake, and the rear end is closed because a second shaft extension is not provided.
