Product Description:

The ADF160C-B05TB1-BS06-A2N1 is a main spindle motor built by Bosch Rexroth Indramat for the ADF Main Spindle Motors series. This unit is intended for continuous-duty machining centers that require stable torque at elevated speeds and repeatable spindle behavior under changing load. Its mechanical interface follows the ADF pattern, and the flange arrangement lets the motor bolt directly to a spindle housing without extra adapter plates or alignment shims. An internal position transducer streams real-time data to the drive controller so that speed, position, and load limits remain under closed-loop supervision during production cycles.

The motor is a liquid-cooled asynchronous motor that channels coolant through the stator jacket to remove heat without external fans. Installation is simplified by flange mounting, which centers the 160 mm frame on the machine wall and maintains alignment under axial loads. Rotor position is reported through digital servo feedback, supplying high-resolution encoder data for velocity and contour-tracking routines. Because the unit is supplied without a holding brake, any required static clamping must be provided by the machine tool itself. Its physical envelope corresponds to size 160 with the C length code, giving a mid-length active core that balances torque density against inertia for milling, boring, and grinding tasks.

The drive side uses a plain shaft with no keyway, which supports shrink-fit tool clamping and helps minimize imbalance. Power conductors terminate in a connector plug located on the top of the housing and routed on Side B, which keeps high-current cabling away from coolant hoses on Side A. This layout also keeps the cable exit clear of the spindle nose area and supports cleaner routing in enclosed machine frames. Dynamic equilibrium meets the R DIN ISO 2373 balance quality grade, reducing vibration transferred to the tool and bearing set during high-speed rotation. The motor is shipped without a shaft seal ring or a second shaft end, and winding code BS identifies the electrical layout used by matched Indramat inverters for spindle control.
