Product Description:

The ADF134C-B05TA0-BS06-A2N2 belongs to the ADF Main Spindle Motors series from Bosch Rexroth Indramat. It is a liquid-cooled asynchronous main spindle motor intended to drive machining centers and other automated tooling stations that require continuous torque at high rotational speeds. By integrating the spindle drive into the machine frame with a flange interface, the motor eliminates belt transmissions and delivers direct, accurate rotation to the workpiece or cutting element.

The rotor is balanced to S DIN ISO 2373, limiting residual vibration during high-speed cutting. Position and speed are closed-loop controlled through digital servo feedback, enabling the CNC to adjust torque in real time. Because the unit is supplied without a holding brake, axial locks or external clamping devices must secure the spindle when power is removed. Mechanical proportions follow the frame code 134 and motor length C, giving the housing the mass and thermal capacity expected for midsize machining centers. Installation uses flange mounting, and this one-piece interface helps maintain precise alignment between the spindle nose and the machine bed. The stator uses winding code BS, and standard rolling bearings support the rotor for general-purpose metal-cutting loads.

Coolant reaches the jacket through an axial connection with a 1/4-inch thread port, so hoses can be routed parallel to the spindle axis and kept clear of guarding. Mains conductors land on a top-side housing that accepts a plug-in connector, and the cables exit toward Side A to match common cabinet layouts. A plain shaft simplifies coupling to precision toolholders, and no shaft-seal ring is fitted because the enclosure already contains the liquid circuit. The design follows the family of liquid-cooled asynchronous motors, and it does not use a second shaft end on Side B so overhang stays minimal while space remains available for encoders or drawbars.
