Product Description:

The ADF160C-B05TA1-BS03-D2N1 main spindle motor is produced by Bosch Rexroth Indramat as part of the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous motor used on machining centers and transfer lines where sustained torque and accurate rotational control are essential. The flange-mounted housing allows direct coupling to the machine headstock, while the integrated motor feedback supports closed-loop positioning through the drive controller. In industrial automation, the unit converts electrical energy into the mechanical rotation required to cut, grind, or drill workpieces with repeatable accuracy. This operating role helps the spindle maintain controlled speed during material removal and rapid transitions between machining steps.

The motor uses flange mounting, and the balance grade R DIN ISO 2373 helps reduce residual vibration. Cooling liquid enters through standard connectors, and the liquid-cooled stator keeps winding temperature stable without external fans. Position data comes from high-resolution motor feedback for fine speed control. The motor uses a shaft with a keyway, balanced with the full key, to transfer torque to the chuck, and a seal ring blocks fluid from the bearings. Standard bearings are fitted, and the motor is supplied without a holding brake so the spindle can run down freely when the system allows it. The BS winding code sets the electrical values expected by the matching drive.

Electrical termination is through a top-mounted connector plug directed to side A of the machine, which simplifies cable routing inside the enclosure. With a frame size of 160 and a build length code of C, the motor offers a compact yet high-power envelope for modern machining centers. The absence of a second shaft end shortens the overall length and leaves room for tooling or drawbar mechanisms at the rear. The top cable exit also helps keep motor leads clear of nearby machine elements and coolant plumbing.
