Product Description:

The ADF104C-B05TA1-CS06-A2N2 is a main-spindle drive engineered by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. Built as a liquid-cooled asynchronous unit, it supplies the continuous torque and thermal stability required for high-speed machining centers and other automated production equipment, converting electrical power into precise spindle rotation under closed-loop control. This operating role helps the spindle maintain stable speed during changing cutting loads and repeated production cycles. It is intended for machine-tool applications that need consistent spindle performance over long runs in enclosed machining spaces.

As a liquid-cooled asynchronous motor, this model routes coolant through standard connection ports to draw heat from the stator so full output can be maintained inside sealed enclosures. Rotor position is returned to the inverter via digital servo feedback, permitting tight speed and torque regulation. Mechanical attachment follows flange mounting, transferring axial forces directly into the machine frame, and the rotor meets S DIN ISO 2373 balance quality to limit vibration at elevated rpm. Electrical behavior is set by the winding code CS, which indicates the impedance and thermal limits for this motor. Standard rolling bearings support the shaft, the coolant fittings use the standard port arrangement, and the power leads exit on Side A through a connector and plug housed in a top-mounted enclosure.

The frame corresponds to motor size 104 and motor length C, delivering a short overall package for medium-diameter toolholders. The unit is supplied without a holding brake, so deceleration is managed electrically by the drive rather than by a mechanical brake assembly. A plain shaft interfaces with the tool spindle, and there is no shaft seal ring or second shaft end, which helps reduce drag and keeps the output end simple. This layout leaves stopping and speed control to the drive without adding brake hardware at the motor. Positioning of the cable box on the housing top keeps chips away from the connector while preserving service clearance inside crowded machine compartments.
